Multirate Anypath Routing in Wireless Mesh Networks - Rafael Laufer
Fri, Mar 27, 2009 @ 10:00 AM - 11:00 AM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract: We present a new routing paradigm that generalizes
opportunistic routing in wireless mesh networks. In multirate anypath
routing, each node uses both a set of next hops and a selected
transmission rate to reach a destination. Using this rate, a packet is
broadcast to the nodes in the set and one of them forwards the packet on
to the destination. To date, there is no theory capable of jointly
optimizing both the set of next hops and the transmission rate used by
each node. We bridge this gap by introducing a polynomial-time algorithm
to this problem and provide the proof of its optimality. The proposed
algorithm runs in the same running time as regular shortest-path
algorithms and is therefore suitable for deployment in link-state routing
protocols. We conducted experiments in a 802.11b testbed network, and our
results show that multirate anypath routing performs on average 80% and up
to 6.4 times better than anypath routing with a fixed rate of 11 Mbps. If
the rate is fixed at 1 Mbps instead, performance improves by up to one
order of magnitude.

Information Theory Applied to Fiber-Optic Transmission: Limits to Spectral Efficiency of Optical Fib
Fri, Mar 27, 2009 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. René-Jean Essiambre
Bell Labs, Alcatel-LucentAbstract: Fiber-optic communication systems constitute the backbone of the communication network infrastructure. The main physical elements of the optical paths in these networks are the optical fiber (as the physical medium for transport) and the optical amplifier (to combat signal attenuation). The transmission bandwidth available over each optical path is enormous, on the order of 10 THz. Despite such a large bandwidth being available, there is a tremendous demand to increase the capacity of fiber-optic communication systems by increasing spectral efficiencies to multiple bits/s/Hz while still maintaining transmission distances on the order of a few thousands of kilometers. Achieving such high spectral efficiency requires using signals with multiple levels in phase and/or amplitude, and possibly using both states of polarization. Transmission of such multilevel signals becomes increasingly impacted by the Kerr fiber nonlinearity, a physical phenomenon unique to the 'fiber channel'. The Kerr nonlinearity results in signal distortions that rapidly increase with signal power. The question then arises: how to apply Shannon's information theory to the `fiber channel' and is there a maximum spectral efficiency associated to the Kerr fiber nonlinearity?In this talk, we will describe how we applied Shannon's theory to the `fiber channel' and present the early results in the direction of conservatively estimating the fiber capacity. A spectral efficiency of ~7 bits/s/Hz (in a single polarization) for transmission over 1000 km in an optically-routed network will be shown to be achievable.Biography: René-Jean Essiambre is a Distinguished Member of Technical Staff at Bell Labs, Alcatel-Lucent. He received his doctorate from Université Laval and studied at the University of Rochester before joining Lucent Technologies (now Alcatel-Lucent) in 1997. Dr. Essiambre is contributing to the design of advanced optical transmission systems, especially in relation to the management of fiber nonlinearities. Interests include modulation formats, detection and optimization techniques for the design of optically routed networks to increase capacity, optical transparency and functionality of wavelength-division multiplexed communication systems. He is a recipient of the 2005 Engineering Excellence Award from OSA, where he is a Fellow.Host: Gerhard Kramer, gkramer@usc.edu, EEB 536, x07229Location: Hughes Aircraft Electrical Engineering Center (EEB) - 248

MIMO HSDPA Testbed Measurements
Fri, Mar 27, 2009 @ 12:00 PM - 01:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Dipl.-Ing. Christian MehlführerAbstract: In this presentation, throughput measurement results of High Speed Downlink Packet Access (HSDPA) are shown. After a short overview about HSDPA and the utilization of multiple antennas in this standard, the measurement methodology and measurement setups in alpine and urban environments are explained. In both environments, the 2x2 and 4x4 MIMO systems achieve more than twice and four times the throughput of the SISO system, respectively. Furthermore, the measured data throughput is compared to an "achievable" throughput that is closely related to channel capacity. This comparison reveals an SNR loss of 6-9 dB, leaving room for improvements.Biography: Christian Mehlführer was born in Vienna, Austria, in 1979. In 2004 he received his Dipl.-Ing. degree in electrical engineering from the Vienna University of Technology. Besides his diploma studies he worked part time at Siemens AG where he performed integration tests of GSM carrier units. After finishing his diploma thesis on implementation and real-time testing of space-time block codes, for which he received the Vodafone Förderpreis 2006 (together with Sebastian Caban), he now is member of the Christian Doppler Laboratory for Design Methodology of Signal Processing Algorithms and works towards his doctoral thesis at the same institute. His research interests include experimental investigation of MIMO systems, MIMO HSDPA (High Speed Downlink Packet Access), MIMO WiMAX (802.16), as well as the upcoming LTE (Long Term Evolution of UMTS) system.Host: Andreas Molisch, molisch@usc.edu, EEB 530, x04670

Dongrui Wu Defense

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Abstract:This research is focused on multi-criteria decision-making (MCDM) under uncertainties, especially linguistic uncertainties. This problem is important because many times linguistic information, in addition to numerical information, is an essential input of decision-making. Linguistic information usually conveys more uncertainty, and it is necessary to incorporate and propagate this uncertainty during the decision-making process because uncertainty means risk.MCDM problems can be classified into two categories: 1) multi-attribute decision-making (MADM), which selects the best alternative(s) from a group of candidates using multiple criteria, and 2) multi-objective decision-making (MODM), which optimizes conflicting objective functions under constraints. Perceptual computer, an architecture for computing with words, is implemented in this dissertation for both categories. For MADM, we consider the most general case that the weights for and the inputs to the criteria are a mixture of numbers, intervals, type-1 fuzzy sets and/or words modeled by interval type-2 fuzzy sets. Novel weighted averages are proposed to aggregate this diverse and uncertain information so that the overall performance of each alternative can be computed and ranked. For MODM, we consider how to represent the dynamics of a process (objective function) by IF-THEN rules and then how to perform reasoning based on these rules, i.e., to compute the objective function for new linguistic inputs. Two approaches for extracting the IF-THEN rules are proposed: 1) linguistic summarization to extract rules from data, and 2) a knowledge mining approach to extract rules through survey. Applications are shown for all approaches proposed in this dissertation.Bio:Dongrui Wu received a B.E in Automatic Control from the University of Science and Technology of China, Hefei, Anhui, P.R. China, in 2003, an M.Eng in Electrical Engineering from the National University of Singapore, Singapore, in 2005, and an MS in Electrical Engineering from the University of Southern California, Los Angeles, CA, in 2008. Currently he is pursuing his Ph.D. in Electrical Engineering at USC. His research interests include computational intelligence, information fusion, machine learning, decision-support systems, signal processing, control theories, and their applications to smart oilfield technologies. Dongrui Wu has more than 20 publications, including a book (co-authored with J. M. Mendel) "Perceptual Computing: Aiding People in Making Subjective Judgments'' by the Wiley-IEEE Press, and a Best Student Paper Award from the 2005 IEEE International Conference on Fuzzy Systems.

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Dr. Carl-Erik W. Sundberg
Visiting Senior Scientist, DoCoMo Labs USA
cews@docomolabs-usa.comAbstract: In this talk we will give a brief overview of the technology building blocks used in current and future digital audio and video broadcasting standards with emphasis on wireless transmission methods, media source coding, digital modulation and channel coding methods. First we will very briefly talk about the early history of broadcasting and analog TV and AM, FM and SW radio. The emphasis is then on wireless digital broadcasting methods including HDTV. We will briefly cover schemes such as digital terrestrial television broadcasting (ATSC, DVB-T, DVB-H, DMB, ISDB-T) and digital audio broadcasting,(Eureka 147,HD Radio, Hybrid IBOC AM and FM, DMB, DRM, MediaFLO ).
The US terrestrial digital audio broadcasting standard HD Radio will be discussed in some detail, especially the FM in band version. In this context we cover some research areas in coding and modulation for the current version of the HD Radio standard as well as for future potential upgrades and modifications of this standard. This includes areas such as complementary punctured pair convolutional (CPPC) codes with optimized bit placement, List Viterbi Algorithms (LVAs) as well as "Dirty Paper Coding" (DPC) type of precoding methods for simultaneous transmission of analog FM and digital data.
We will also briefly look at complementary methods of audio and video broadcasting such as satellite, cable and fiber transmission and internet streaming. Finally we will discuss the convergence of digital broadcasting with 3G (e.g. Media Broadcast and Multicast Service, MBMS) and 4G cellular technologies as well as speculate about future wireless broadcasting methods.References:

MOBILE IMAGE MATCHING - TOWARDS MOBILE AUGMENTED REALITY
Fri, Mar 27, 2009 @ 04:00 PM - 05:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Professor Bernd Girod,
Department of Electrical Engineering
Stanford UniversityAbstract: Hand held mobile devices, such as camera phones or PDAs, are expected to become ubiquitous platforms for visual search and mobile augmented reality applications. For mobile image matching, a visual database is typically stored at a server in the network. Hence, for a visual comparison, information must be either uploaded from the mobile to the server, or downloaded from the server to the mobile. With relatively slow wireless links, the response time of the system critically depends on how much information must be transferred. We review recent advances in mobile matching, using a "bag-of-visual-words" approach with robust feature descriptors, and show that dramatic speed-ups are possible by considering recognition and compression jointly. Real-time implementations of different applications, such as recognition of landmarks or CD covers, demonstrate the relative advantages of image processing on the phone, the server, and/or both.Biography: Bernd Girod is Professor of Electrical Engineering and (by courtesy) Computer Science in the Information Systems Laboratory of Stanford University, California. He was Chaired Professor of Telecommunications in the Electrical Engineering Department of the University of Erlangen-Nuremberg until 1999. His research interests are in the areas of video compression, networked media systems, and image databases. He has published over 400 conference and journal papers, as well as 5 books.
