Estimation Theory and Mutual Information
Wed, Nov 02, 2005 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Sergio Verdu, Princeton UniversityAbstract: For signals observed in Gaussian noise, there are several interesting intersections between information theory and linear and nonlinear minimum mean-square error (MMSE) estimation. We have shown a new relationship between the input-output mutual information and the MMSE achievable by the optimal estimator of the input. This relationship holds for arbitrarily distributed scalar and vector signals, as well as for discrete-time and continuous-time noncausal MMSE estimation (smoothing). We have also recently shown the counterpart of these results in discrete-input discrete-output channels. I will also discuss several applications of these information theoretic results: the mercury/waterfilling formula for power allocation with arbitrary input constellations; a universal continuous-time nonlinear filtering formula that couples the signal-to-noise ratios achievable by smoothing and filtering; and a very simple proof of the entropy-power inequality.Bio: Sergio Verdú is a Professor of Electrical Engineering at Princeton University where he teaches and conducts research on information theory.In 1998, Cambridge University Press published his book "Multiuser Detection," which received the Frederick E. Terman Award from the American Society for Engineering Education. His papers have received several awards: the D.

Indian Institute of Technology A major attention of micromachining technology has recently been focused on miniature inertial sensors. Rapid advancement of micromachined accelerometer technology has enabled cost effective high performance micro accelerometers that revolutionizes the traditional accelerometer market. Apart from commercial and consumer applications, one major applications of miniature high precision accelerometer is in the field of avionics and space. This lecture deals with the development of both silicon and quartz micromachined MEMS accelerometers and gyros for avionics and space applications. An accelerometer of the range of âb 13 g with very low off-axis acceleration, a resolution of âb 2 mg and a linearity of less than 1% has been designed and fabricated. As the piezoresistive accelerometers are less susceptible to parasitic capacitance and electromagnetic interference, we opted for the same because of simple fabrication process and read out circuitry. The piezoresistive accelerometer consists of a silicon base, a proof mass supported by double cantilever beam and cap layers. Coventorware 2001.3 software package has been used to design the accelerometer. Simulation results indicate that the maximum output voltage under 13 g acceleration along z-axis is nearly 20 mV with 5 volts bridge supply whereas off-axis response is about 3-4 order less than z-axis response, which is one of the requirement of the navigational grade accelerometers. TMAH based five mask accelerometer technology has been indigenously developed at IIT Kharagpur and the MEMS accelerometers were fabricated, bonded and packaged. Interface electronics for the MEMS accelerometer has been designed and the chips were tested with available facilities. Characterization of the chip has been conducted up to âb 10 g and results are found to be highly encouraging. Plot of acceleration with output voltage is found to be highly linear (< 1 %) and with negligible offset value. The off-axis sensitivity was less than nearly two orders of magnitude than z-axis acceleration. IIT Kharagpur was the first in India to develop quartz micromachining technology. The indigenous development of the quartz technology is considered significant because quartz micromachining is protected technology with very little details are available in scientific literature. We have made use of this technology to fabricate tiny dual tuning fork structures with built-in electrodes via flexures, for sensing rotation (gyro), and double-ended tuning forks (DETF) used in MEMS accelerometers. This lecture also covers design and fabrication of quartz double-ended tuning fork accelerometer and dual tuning fork gyros.Location: Olin Hall of Engineering (OHE) - 230

Antenna selection and RF preprocessing for MIMO systems
Tue, Nov 08, 2005 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Andreas Molisch, Mitsubishi Electric Research LabsAbstract: Multiple Input Multiple Output (MIMO) systems can significantly increase the capacity of a wireless link and improve the robustness of the link. However, an important factor limiting the adoption of MIMO is the increased system- and hardware complexity. The signal received (transmitted) at each antenna element requires a separate Radio Frequency (RF) demodulator (demod) chain, which is expensive. A way to mitigate this problem is antenna selection, where either one, or both, link ends choose the "best" out of available antennas, so that only L (instead of N) RF chains are required. This talk will give an overview of the performance of antenna selection schemes when used in conjunction with diversity or with spatial multiplexing. In ideal channels, full diversity order can be achieved, and also the number of independent data streams for spatial multiplexing can be maintained if certain conditions on are fulfilled. However, there is a reduction of beamforming gain, which can lead to a significant performance loss especially in correlated channels. We will then demonstrate that a preprocessing of the signals in the RF domain by an array of phase shifters can recover most of this beamforming gain. A discussion of the hardware nonidealities in the preprocessing scheme and their impact on the performance wraps up the talk.Bio: Andreas F. Molisch (Fellow, IEEE) is a senior researcher with Mitsubishi Electric Research Labs (Cambridge, MA), and professor for radio systems at Lund University, Sweden. Previously, he had worked at AT&T Bell Labs (NJ) and the Technical University of Vienna, Austria. His current research interests are wireless propagation channels, MIMO systems, and ultrawideband (UWB) systems. He has authored, co-authored, or edited four books, 11 book chapters, some 85 journal papers, and numerous conference contributions. He is inventor of more than 40 patents, has been chairman of various standardization and industrial groups in the area of MIMO and UWB, and received several awards.Host: Keith Chugg, chugg@usc.edu, x.07294

Exact quantum circuits for measuring entanglement
Wed, Nov 09, 2005 @ 03:00 PM - 04:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Hilary Carteret, University of CalgaryAbstract: There has recently been a lot of interest in techniques for measuring the non-local properties of a density matrix as efficiently as possible. These functions are often defined in terms of unphysical maps, such as the partial transpose. Previous proposed methods for measuring these quantities relied on full state tomography (very inefficient) or the Structural Physical Approximation, which adds large amounts of noise to shift the spectrum of the partially transposed density matrix to be positive, thus incurring a corresponding loss of sensitivity. The moments of the resulting modified density operator are measured using certain sets of generalized Mach-Zehnder interferometers and the spectrum can then be determined using a little algebra.I will show how to construct a family of simple circuits that can determine the spectrum of the partial transpose of a density matrix, without the addition of noise. These circuits depend only on the dimension of the density matrix and do not need any components that are not already required to determine the eigenspectrum of the original density matrix by interferometry. They measure the minimum amount of information required to determine the PT-spectrum completely and they will be exact up to experimental errors.If we get time, I can discuss some extensions to this construction which can be used to measure the concurrence and related entanglement monotones.Bio: Hilary Carteret was born in London, England. She did her D.Phil. in Mathematics at the University of York, working for Tony Sudbery. After six months working in the QOLS group in Imperial College, she moved to Canada, where she has held postdoctoral fellowships at the University of Waterloo (IQC) and then the Universite de Montreal. She has just moved to the new Institute for Quantum Information Science at the University of Calgary, to work with Barry Sanders.Host: Professor Todd A. Brun, tbrun@usc.edu, x. 03503

DISTINGUISHED LECTURER SERIES"The History and Future of the
Integrated Circuit"Prof. Thomas Lee
Stanford UniversityGerontology Auditorium (GER-124)Thursday, November 17, 20052:00-3:00p.m.[A reception will follow at 3:00p.m.]Abstract:Moore's law is rapidly approaching the half-century mark, and many wonder how much longer it can work its magic. This talk doesn't presume an answer to that question, but instead looks at the history of the semiconductor age to suggest possible futures. There will be a focus on the much-underappreciated role of chance in creating semiconductor technology. Relatively few engineers are aware that diodes were a 19th-century discovery, and that the PN junction and even doping were discoveries, the latter aided by a pair of sensitive noses. The path to the future will likely require similar fortuitous discoveries, aided by Pasteur's famous "prepared minds.Bio:Thomas H. Lee received the S.B., S.M. and Sc.D. degrees in electrical engineering, all from the Massachusetts Institute of Technology in 1983, 1985, and 1990, respectively. He joined Analog Devices in 1990 where he was primarily engaged in the design of high-speed clock recovery devices. In 1992, he joined Rambus Inc. in Mountain View, CA where he developed high-speed analog circuitry for 500 megabyte/s CMOS DRAMs. He has also contributed to the development of PLLs in the StrongARM, Alpha and AMD K6/K7/K8 microprocessors. Since 1994, he has been a Professor of Electrical Engineering at Stanford University where his research focus has been on gigahertz-speed wireline and wireless integrated circuits built in conventional silicon technologies, particularly CMOS. He has twice received the "Best Paper" award at the International Solid-State Circuits Conference, co-authored a "Best Student Paper" at ISSCC, was awarded the Best Paper prize at CICC, and is a Packard Foundation Fellowship recipient. He is an IEEE Distinguished Lecturer of both the Solid-State Circuits and Microwave Societies. He holds 35 U.S. patents and authored The Design of CMOS Radio-Frequency Integrated Circuits (now in its second edition), and Planar Microwave Engineering, both with Cambridge University Press. He is a co-author of four additional books on RF circuit design, and also cofounded Matrix Semiconductor.Host: Prof. John Choma, x04692Location: Ethel Percy Andrus Gerontology Center (GER) - ontology Auditorium

CENG SEMINAR SERIESTechnological Challenges in Building and Managing Utility Computing GridsDr. Rajkumar BuyyaGrid Computing and Distributed Systems (GRIDS) LaboratoryDept. of Computer Science and Software EngineeringUniversity of Melbourne, AustraliaAbstract:Grid computing, one of the latest buzzwords in the ICT industry, is emerging as a new paradigm for Internet-based parallel and distributing computing. It leverages existing IT infrastructure to optimize compute resources and manage data and computing workloads. The developers of Grids and Grid applications need to address numerous challenges: security, heterogeneity, dynamicity, scalability, reliability, service creation and pricing, resource discovery, resource management, application decomposition and service composition, and qualify of services. To address some these challenges, the Gridbus Project at the University of Melbourne has developed grid middleware technologies that support rapid creation and deployment of eScience and eBusiness applications on enterprise and global Grids. In this seminar, we place emphasis on fundamental challenges of Grid economy, how to design and develop Grid technologies and applications capable of dynamically leasing services of distributed resources at runtime depending on their availability, capability, performance, cost, and users' quality of service requirements. We briefly present various components of the Gridbus Toolkit and then discuss, in detail, the Gridbus service broker that supports composition and deployment of applications on utility Grids. Case studies on Gridbus middleware in creation of Grid applications on international Grids will be highlighted.Biographical Sketch :Dr. Rajkumar Buyya is a Senior Lecturer, Storage Technology Corporation (StorageTek, USA) Fellow of Grid Computing, and the Director of the Grid Computing and Distributed Systems (GRIDS) Laboratory within the Department of Computer Science and Software Engineering at the University of Melbourne, Australia.

Quantum informations first family, revisited

Speaker: Dr. Patrick Hayden, McGill UniversityAbstract: It's been almost two years since Devetak, Harrow and Winter introduced their "mother" and "father" protocols into quantum information theory. In their paper, almost all of the many varieties of capacity and distillation protocols that had been previously been devised in quantum information theory were organized into two sets of children, those descended from the mother and those descended from the father. In this talk, I'll sketch a new and very simple proof of the mother protocol. Along the way, she'll reveal herself to be even more powerful than previously thought. In addition to generating optimal entanglement distillation protocols, I'll show how she provides a straightforward proof of the Horodecki-Oppenheim-Winter negative information result and can be used as a building block for the distributed compression of quantum data. In her new, more powerful form, the mother protocol even generates the father. The original two sets of children are thereby reduced to one and our understanding of quantum information theory is radically simplified: by starting with a single maximally quantum-mechanical protocol and transforming it in a few simple ways we can accomplish most of the tasks of interest in two-party quantum information processing.Bio: Patrick Hayden is currently an assistant professor of computer science at McGill University. Prior to joining McGill in 2004, he spent three years as a Sherman Fairchild Prize Postdoctoral Fellow at the California Institute of Technology. He obtained his D.Phil. in physics as a Rhodes Scholar at Oxford University and a B.Sc. in mathematics and physics from McGill. His current fascination with quantum information processing was foreshadowed early; as a high school student, he worked summers as a programmer for an operating systems company with the curiously prescient, if premature, name Quantum Software Systems.Host: Professor Igor Devetak, devetak@usc.edu
