Talk Title: Distributed MIMO: Theory, Architecture and Implementation
Abstract: MIMO systems have received tremendous attention from the research community in the last decade. By increasing the number of antennas at the transmitter and/or receiver, it is possible to increase communication range, link quality, reduce interference etc. The idea of Distributed MIMO (D-MIMO) is to exploit the potential benefits of MIMO with SISO terminals: different single-antenna terminals can be combined to create a “virtual” antenna array. In this talk, two particular sub-problems of D-MIMO will be investigated: distributed transmit (D-Tx) beamforming and distributed receive (D-Rx) beamforming.
The biggest challenges of D-MIMO systems are the different levels of synchronization that must be achieved among the different terminals to operate a virtual array, and the scalability to larger network sizes. Three types of synchronization are required: frequency, phase and timing. The frequency offset results from the fact that each node has its own local oscillator (LO), and small LO offsets between nodes may result in large LO frequency offsets. The phase synchronization is needed because the path lengths between the different nodes are unknown. The timing offset is due to the fact that each node has its own clock, and common time references are needed to align the clocks of all the nodes. Solutions for these problems must always take scalability into account: for larger networks, it is important not to drown the network with control messages.
For both the D-Tx and D-Rx beamforming, we will present architectures that are able to tackle the synchronization issues while maintaining scalability to larger networks. Synchronization is achieved with feedback-based strategies that are able to synchronize the nodes of the virtual array; even with low-quality local oscillators typically used for software-defined radios. The proposed architectures are investigated theoretically, and closed-form expressions for the limits of our architecture are deduced. Finally, for both D-Tx and D-Rx beamforming, the proposed architecture is implemented on our software-defined radio testbed. Our experiments show with appropriate design, the potential benefits of D-MIMO can be achieved with low-cost radios.

Refractive Index Engineering by Fast Ion Implantations: A Generic Method for Constructing Multi-components Electrooptical Circuits

Speaker: Aharon J. Agranat, The Hebrew University of Jerusalem
Talk Title: Refractive Index Engineering by Fast Ion Implantations: A Generic Method for Constructing Multi-components Electrooptical Circuits
Abstract: Refractive index engineering (RIEng) by ion implantations in electrooptical substrates is a generic methodology for constructing multi-component integrated circuits of electrooptic and nanophotonic devices with sub-wavelength features operating in the visible - near IR wavelengths. RIEng exploits the fact that ions that are incident at high energies on a substrate of oxygen Perovskites form within the depth of the substrate a well confined layer of Frenkel defects which cause the layer to be partially amorphized. The refractive index in this layer differs significantly from that of the crystalline substrate. It was also found that the waveguiding structures are thermally stable after being subjected to an annealing process, and exhibit a propagation loss of 0.1 dB/cm.
The essence of the method is to perform spatially selective implantations for sculpting complex 3D pre-designed patterns with reduced refractive index within the volume of the substrate. Sculpting 3D structures is enabled by combining three techniques that form a complete toolbox for constructing the circuits: (i) Lateral patterning: defining the lateral distribution of the amorphization by performing the implantation through a “stopping mask” which causes the amorphized region to replicate the contour of the topography of the mask; (ii) Longitudinal patterning: determining the depth of the amorphized region by controlling the energy of the implanted ions; and (iii) Selective etching: selective etching of the amorphized material that were created by the implantation process. In addition to these, the 3D structures can be made to be electrically conductive and photoconductive by using high fluence of protons as the implanted species. RI Eng was also combined with laser ablation to form structures with high contrast of the difference in the refractive index between the core and the cladding.
A number of devices that were constructed in a substrate of potassium lithium tantalate niobate will be described, including an optical wire, a channel waveguide array, a protons grating, and a waveguide constructed by a combination of laser ablation and implantation of alpha particles.
Biography: Professor Ronny Agranat is the director of the Brojde center for innovative engineering and computer science, and the incumbent of the Nahman Jaller chair of Applied Science at the Hebrew University of Jerusalem. Agranat holds a B.Sc degree in physics and mathematics (1977), an M.Sc degree in Applied Physics (1980), and a PhD degree in physics (1986) all from the Hebrew University of Jerusalem. His Ph.D thesis was on the subject of the dielectric mechanism of the photorefractive effect which he discovered. From 1986 to 1997 he was a senior research fellow and a visiting senior research associate at the California Institute of Technology (Caltech), where he worked on the development of microelectronic artificial neural networks based on charge transfer devices which he invented, and the growth and investigation of paraelectric photorefractive crystals. In 1991 he joined the faculty of the Hebrew University of Jerusalem and founded the optoelectronic computing laboratory. The laboratory mission is to conceive and develop optoelectronic devices and systems that will expand the capabilities of the computing and communication technologies that are the physical basis of the cyberspace. One of the main themes pursued by Agranat is to exploit the special features of the quadratic electrooptic effect at the paraelectric phase for the purpose of constructing various optoelectronic device, in particular for wavelength selective switching applications. To that end Agranat invented and developed a new electrooptic crystal: potassium lithium tantalate niobate (KLTN). Agranat is the inventor of Electroholography which is a generic optical switching method based on governing the reconstruction process of volume holograms by the applications of electric fields. Electroholography was invented for the purpose of interconnecting electronic processors by holographic devices. In particular it has been identified as the leading concept for dynamic wavelength selective routing in WDM optical fiber communication networks. For the invention of Electroholography and the KLTN crystal Agranat was awarded the Discover Innovation Award (awarded by the Discover magazine and the Christopher Columbus Society) for the leading invention in the area of communication for the year 2001. Agranat is a member of the Hebrew University Interdisciplinary Center of Neuro-Computing, and a fellow of the Optical Society of America. Agranat was also a cofounder and director of TrellisâPhotonics that was founded for exploiting Electroholography in telecommunication applications. Agranat is the author of many scientific papers, and holds 24 patents in the areas of microelectronics, optoelectronics and materials science.

Talk Title: Behavioural Modeling & Linearization of RF Power Amplifiers
Abstract: In cellular wireless communications systems, the RF power amplifier (PA) in the transmitter must be as efficient as possible, to minimize energy costs, to prolong battery life, and for âgreen’ considerations. Modern spectrally-efficient, digitally-modulated signals such as LTE and UMTS present a challenge for efficient RF PA design, and the power amplifier architectures that are adopted to achieve this goal are generally very nonlinear, and so some form of linearization technique is necessary.
The increasing use of linearization techniques, and especially the emergence of high speed digital processing as an enabling technology to implement digital pre-distortion (DPD) of the PA input signal, represent an important paradigm shift in PA design. The PA component can now be designed with more emphasis on power and efficiency, without the traditional constraints of meeting stringent linearity specs simultaneously. Understanding the utility of a linearizer to obtain optimum efficiency has thus become a new subject area in modern RF PA design.
The system-level design of linearized PA transmitters requires accurate models to achieve the optimal performance. Behavioural modeling is used to describe the PA and linearizer at this level of the design. In this tutorial, we shall present some approaches to the behavioral modeling of nonlinear dynamical systems that can be used to model RF PAs; particular emphasis will be given to the treatment of memory effects. Some common mathematical and systematic approaches to model generation will be presented, to obtain accurate but compact nonlinear dynamical models. A brief description of some characterization techniques will be included. These same nonlinear modeling techniques can be applied to the design of successful pre-distortion algorithms. We shall illustrate the overall structure of a linearized transmitter using several DPD architectures, and we shall present various approaches to adaptive pre-distortion, considering such features as convergence, signal bandwidth, accuracy, and cost.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Shamgar Gurevich, University of Wisconsin - Madison
Talk Title: Algebraic Symmetries of Digital Signal Processing
Abstract: We will explore basic algebraic symmetries of spaces of sequences that are used in digital signal processing (DSP). There are two types of symmetries: (1) The Heisenberg (after Werner Heisenberg) symmetries, which generalize the time-shift and frequency-shift operators. (2) The Weil (after Andrei Weil) operators which generalize the discrete Fourier transform (DFT). We will look on two applications: (I) Construction of the Heisenberg (Chirp) sequences---which are commonly used in radar systems---and relations among them. (II) Efficient calculation of the Radar Ambiguity Function on a general line in the discrete time-frequency plane. These applications will be used by Alexander Fish in his lecture "The Cross Method for Multi-Target Radar Detection".
The lecture is part from a joint work with: Alexander Fish (Sydney), Akbar Sayeed (EE, Madison), Oded Schwartz (EECS, Berkeley).
Biography: Shamgar Gurevich is a faculty in the mathematics department of the University of Wisconsin Madison. He is doing research in topics of algebra which are related to sequences design for wireless communication and related algorithms for GPS, Radar, and Communication.

Speaker: Alexander Fish, University of Sydney
Talk Title: The Cross Method for Multi-Target Radar Detection
Abstract: We would like to know the distances to moving objects and their velocities. The radar system is built to fulfill this task. The radar transmits a waveform S which bounds back from the objects and the echo R is received. In practice we can work in the digital model, namely S and R are sequences of N complex numbers.
THE RADAR PROBLEM IS: Design S, and an effective method of extracting, using S and R, the distances and velocities of all targets.
In many applications the current sequences S which are used are pseudo-random and the algorithm they support takes O(N2logN) arithmetic operations. In the lecture we will introduce the Heisenberg sequences, and a much faster detection algorithm called the Cross Method. It solves the Radar Problem in O(NlogN+m2) operations for m objects.
This is a joint work with Shamgar Gurevich (Math, Madison), Akbar Sayeed (EE, Madison), Kobi Scheim (General Motors, Israel), Oded Schwartz (EECS, Berkeley)

Talk Title: Energy Aware High Performance Computing
Series: EE598 Seminar Course
Abstract: Power or Energy usage for various systems became an issue because of cost and efficiency. As the goal of advancing or enhancing a computing system is to increase or enhance the performance, it is not enough just to decrease the power or energy usage. Therefore, while trying to minimize the power usage the performance of the system must be upgraded. There are many environments or systems that must consider both energy and performance for enhancement at the same time. Distributed mobile computing is one such environment where computing resources are mobile, connected wirelessly, have limited battery power, and may be heterogeneous from one another. A multi-core chip multiprocessor can be another such system that may need an intelligent method to reduce the energy usage while also trying to enhance performance.
Biography: Jong-Kook Kim is currently an Associate Professor at Korea University, Seoul Korea. He received his M.S. and Ph.D. degrees in electrical and computer engineering from Purdue University in May 2000 and August 2004, respectively.

His research interests include heterogeneous distributed computing, real-time mobile computing, computer architecture, performance measures, resource management, evolutionary heuristics, energy-aware computing, and distributed compilers. He is a member of the IEEE, IEEE Computer Society, and ACM.

Speaker: Emanuele Viterbo, Monash University, Melbourne Australia
Talk Title: Twenty Years of Sphere Decoding
Abstract: The sphere decoding algorithm was first introduced in digital communications in 1993. This algorithm provides a practical solution to an otherwise NP-complete problem (ML decoding for multidimensional lattice constellations over fading channels). This work has been cited to date in over 1200 papers (source: scholar.google) and this number is steadily growing. The pioneering use of lattice decoding of codes for single antenna systems has been followed by a substantial body of research showing the use of the sphere decoder in many other applications, among which decoding of space-time codes for MIMO. More re cently, the sphere decoding algorithm has been implemented in VLSI, for high rate wireless LAN terminals. This talk will present the basic principle of sphere decoding and its historical development into communications engineering.

Speaker: Konrad Lehnert, University of Colorado and NIST
Talk Title: “Micro-electromechanics: A New Quantum Technology”
Abstract: That an object can be in two distinct places simultaneously is a consequence of quantum theory and a fact routinely invoked to account for the behavior of electrons and atoms. Nevertheless, these superpositions are in conflict with our everyday experience. What is the largest and most tangible object that can be prepared in such a superposition? This question has motivated researchers to fabricate micron-scale mechanical resonators and coax them towards the regime of quantum behavior. Indeed micro-mechanical devices recently reached the quantum regime.
In this talk, I will describe how we use electricity to achieve the exquisite control and measurement of micro-mechanical resonators necessary to reach the quantum regime. Having entered this regime, we are now able to pursue many exciting ideas. We endeavor to use mechanical resonators as long-lived memories for the quantum states of electrical circuits. In addition, we are developing the technology to transfer quantum states between two incompatible systems via a mechanical intermediary. In the future, it may even be possible to test quantum theory itself in an unexplored region of mass and size scales.

Talk Title: Light Matter Interaction at the Nano-scale: Towards Attojoule Optoelectronics
Abstract: Understanding and engineering light-matter interactions hold the key to solving several important problems in modern society, including but not limited to high performance computing and communication. To enable optical interconnects over short distances between electrical components, and in the future even performing the whole computing process in the optical domain, the energy consumption must be decreased to several attojoules per bit. In my talk, I will describe how such attojoule optoelectronic technologies can be developed by engineering light-matter interactions at the nano-scale.
First, I will describe the coupled quantum dot (QD)-cavity system. Very strong interaction between light and matter can be achieved in this system as a result of the field localization inside sub-cubic wavelength volumes. Such strong light-matter interaction produces an optical nonlinearity that is present even at the single-photon level and is tunable at a very fast time-scale (~few picoseconds). We use this effect to perform very low power optical and electro-optical modulation. Although this system provides us with light-matter interaction at the most fundamental level and the cavities can be scaled very easily, the growth of self-assembled QDs ultimately limits the scalability of this coupled system. As a route to overcome this problem, I will describe another system: the graphene-clad photonic crystal cavity, where we have also demonstrated electro-optic modulation. With the light-matter interactions controlled at a very low energy level, these nano-photonic devices pave the way towards reaching attojoule optoelectronics.

Talk Title: High-Performance Networking on Reconfigurable Fabric
Series: EE598 Seminar Course
Abstract: The Internet is growing at a rapid pace with the proliferation of multimedia applications such as VoIP, video streaming and gaming. This rapid growth is facilitated by the underlying networking hardware, which is responsible for meeting Quality of Service (QoS) requirements while guaranteeing the throughput demands of a network. In this talk, we discuss how such time-critical tasks can be algorithmically mapped on to reconfigurable hardware platforms such as Field Programmable Gate Array (FPGA), exploiting the massive parallelism offered in these devices. Methodologies to device 100+ Gbps hardware firewalls that consume orders of magnitude lower power than state-of-the-art solutions will be presented.

Speaker: Shlomo Shamai, Technion â Israel Institute of Technology
Talk Title: Coding Over Interference Channels: An Information-Estimation View
Abstract: The information-estimation relation is used to gain insight into useful coding schemes operating over the Gaussian interference channel. After reviewing basic I-MMSE relations and their implications on point-to-point coding over the Gaussian channel, we focus on the Gaussian interference channel. Here the inflicted interference is measured by the associated minimum mean square error (MMSE). Structure of codes achieving reliable communication at some specific signal-to-noise ratio (SNR) and constrained by the permitted MMSE at a lower SNR values, modeling the interference, are discussed. It is shown that layered superposition codes attain optimal performance, providing thus some engineering insight to the relative efficiency of the Han-Kobayashi coding strategy. The Degrees-of-Freedom (DoF) behavior of the multi-user Gaussian interference channel is captured by considering the MMSE-Dimension concept, providing a general expression for the DoF. A short outlook concludes the presentation, addressing related research challenges, and also recent results, where interference is measured by the corresponding mutual information.

Talk Title: Microwave GaN Power Amplifiers for Efficient Communication and Radar Transmitters
Abstract: This talk will present an overview of the activities in the microwave and antennas group at the University of Colorado, Boulder, followed by a more detailed discussion of various techniques for obtaining high-efficiency transmitters for non-constant envelope communication and radar signals. Several efficient amplifiers will be presented, for applications such as wind-profiling radar with 3-kW LDMOS pulsed 449-MHz PAs with power added efficiencies (PAE) greater than 65%, to S-band hybrid GaN PAs with 10W output power and PAE>80% and X-band 10-W MMIC GaN PAs with PAE>60%. These amplifiers are integrated into transmitters that use several architectures to maintain efficiency for varying amplitude signals, such as supply modulation, outphasing and harmonic injection at the output. Several transmitters for envelope signal bandwidths exceeding 100MHz, over 6dB peak-to-average ratios, and total system efficiencies greater than 50% will be presented. Since high efficiency is accompanied with high nonlinearity, techniques for linearization will also be discussed.

Talk Title: Energy Efficient and Reliable GPGPU Architecture
Series: EE598 Seminar Course
Abstract: Graphics Processing Units (GPUs) are initially designed to provide a high performance computing for multimedia applications. Due to the efficiency of their execution model, nowadays GPUs are used to run scientific, medical and financial workloads in addition to the multimedia workloads. In this talk we will explore the opportunities in current GPUs that can be used to support a reliable and power efficient execution without affecting the overall performance of GPUs.
In the first part of the talk we will go through some workloads characterization experiments to explore the available opportunities for reliable and power efficient solutions. In the second part we will introduce two mechanisms based on the explored opportunities. The first mechanism is warped DMR that focuses on designing a reliable execution model in GPUs in order to match with the reliability requirements for the new set of application domains. The second mechanism is warped register file that targets designing a power efficient register file for GPUs in order to mitigate the wasted leakage and the dynamic power caused by the mismatch in applications requirements.

Talk Title: High Data Rate Communications: Solutions and Challenges
Abstract: Bandwidth growth is a key driver for performance growth in a wide range of arenas, especially including servers and high performance ASICs. Yet while mixed-signal circuits do not accrue nearly the scaling-derived improvements in power-per-operation as do digital processing circuits, desired bandwidth growth must nevertheless be delivered in the context of power constraints that are increasingly inflexible. This presentation will first provide an overview of work underway in the Communication and Computation Subsystems department within IBM Research, and will then focus on key solutions and challenges regarding high data rate communications for future systems applications. Example designs discussed will illustrate the continuing interplay and evolution of the roles of architecture, packaging, mixed-signal design, and technology in addressing the bandwidth needs of future computing systems.
Biography: Daniel Friedman received the Ph.D. degree in Engineering Science from Harvard University. After completing post-doctoral work in image sensor design, he joined IBM Research, initially to work on analog circuits and air interface protocols for field-powered RFID tags. In 1999, he began working on analog circuit design for high-speed SerDes macros and became manager of a team focused on I/O and PLL designs shortly thereafter. He is now senior manager of the communication circuits and systems department, which includes groups working on mixed high speed analog/digital design, mmWave design, and FPGA designs; he also chairs the wireline sub-committee of ISSCC.

Talk Title: Electronics Without Borders: Moving Towards Any Semiconductor âX’ on Any Substrate âY’
Abstract: Pushing the boundaries of electron devicesâfrom transistors to photovoltaicsâdemands complete control over device architectures and material systems. However, traditional growth and fabrication techniques often fall short when optimal design calls for non-planar geometries or integration of non-epitaxial material systems.
Thus, development of techniques for X-on-Y growth and integration, such as: (i) bottom-up growth of geometry and shape-controlled nanowires, (ii) integration of dissimilar material systems such as III-V’s and Si, and (iii) direct growth of high-quality semiconductors on metals are critical. In this talk, I discuss how semiconductor layer transfer techniques can be used to fabricate high-mobility III-V transistors on Si substrates, and the vapor-liquid-solid (VLS) growth mode can be used to grow templated nanowires and high-quality InP thin films directly on metal foils.
Specifically, I will cover three methods that move towards enabling X-on-Y. First, I will show a compound semiconductor on insulator (XOI) layer transfer technique that enables integration of free-standing, ultra-thin III-V membranes on Si substrates. The second method is a templated VLS nanowire growth technique for 3-D semiconductor structures on metal substrates. The last technique I illustrate is a thin-film vapor-liquid-solid growth technique for the direct growth of large grain (10-100 micron) polycrystalline InP on metal substrates.
Biography: Rehan Kapadia is currently a graduate researcher at the University of California, Berkeley. He is a National Science Foundation Graduate Student Fellow, and has published 24 journal articles, in journals such as Nature, Applied Physics Letters, Nano Letters, and Advanced Materials. He received a B.S. in Electrical Engineering from the University at Texas at Austin, M.S from UC Berkeley and will receive his Ph.D from UC Berkeley May 2013. His research interests center on material growth techniques that enable high-performance, scalable electronics, with a focus on energy devices.

Talk Title: Energy Proportional Datacenter Servers
Series: EE598 Seminar Course
Abstract: Energy proportionality (EP), the notion where power consumption should be proportional to utilization, is becoming an increasingly important concept in datacenter servers. In this talk, we introduce metrics to accurately quantify energy proportionality and analyze historical EP trends to identify opportunities to improve EP. We find that there exists large energy proportionality gap at low utilization and we present KnightShift, a server-level heterogeneous server that introduces an active low-power mode through the addition of a tightly-coupled compute node called the Knight. We evaluated KnightShift against a variety of real-world datacenter workloads using a combination of prototyping and simulation, showing up to 75% energy savings with tail latency bounded by the latency of the Knight and up to 14% improvement to Performance per TCO dollar spent.
Biography: Daniel Wong is a PhD student working with Prof. Murali Annavaram in the Ming Hsieh Department of Electrical Engineering at the University of Southern California, Los Angeles. His research focuses on novel energy efficient architectures spanning from datacenter servers to GPGPUs.
