Research Stemming from the Development of a MIMO OFDM

Free and open to the public
Light refreshments will be served
Over the course of the past few years, the UCLA Wireless Communications and Integrated Systems (WISR) group has been active in the development of highly versatile MIMO OFDM testbed for experimental high speed wireless data communications. This exercise inspired several inherently multi-disciplinary research projects that simultaneously look at the interplay between circuits and algorithms. Using the testbed development as the underlying theme, this talk will feature three such projects. The first involves the design of a highly versatile MIMO decoder accelerator core, a highly programmable VLSI architecture that will deliver the versatility needed to implement any one of a number of distinct MIMO protocols. The second is a link adaptation protocol that aims to minimize energy consumption by optimal setting of the PHY algorithms as well as the analog, RF, and baseband circuit parameters. The third is a spatial interference mitigation engine meant for packet based wireless systems that cleans the incoming interference and allows a traditional receiver to operate unhindered. The talk concludes by a live demonstration of the MIMO OFDM testbed supporting data rates from 1.5 Mbps to 150 Mbps, and an invitation to the audience to experiment with the nodes.
About the Speaker:
Babak Daneshrad, Ph.D., is a professor with the Electrical Engineering Department at the University of California, Los Angeles (UCLA). His research interests are in the areas of wireless communication system design, experimental wireless systems, and VLSI for communications. He obtained B.Eng.and M.Eng. degrees with emphasis in communications from McGill University, in 1986 and 1988 respectively, and a Ph.D. degree from UCLA in 1993 with emphasis in integrated circuits and systems. His current research interests are cross disciplinary in nature and deal with addressing practical issues associated with the realization of advanced wireless systems. The work is focused on low power MIMO wireless systems, as well as cognitive radio communications.
He is the recipient of the 2005 Okawa Foundation award, a co-author of the best paper award at PADS 2004, and was awarded first prize in the DAC 2003 design contest. He is the beneficiary of the endowment for "UCLA-Industry Partnership for Wireless Communications and Integrated Systems". In January 2001 he co-founded Innovics Wireless, a company focused on developing 3G-cellular mobile terminal antenna diversity solutions, and in 2004 he co-founded Silvus Communications. Formerly, from 1993 to 1996 he was a member of Technical Staff with the Wireless Communications Systems Research Department of AT&T Bell Laboratories where he was involved in the design and implementation of systems for high-speed wireless packet communications.
