Abstract : Interference is a central phenomenon in wireless communication. Multiple wireless links compete for shared resource via interference. But what exactly is the resource being competed for? From a physical layer perspective, traditional collision-based models are too crude as they do not take into account the channel strengths of the interfering links. Building on recent progress in the information theory of interference channels, a new abstraction of wireless resource is proposed. Using this new abstraction, the following questions will be answered: 1) What is the optimal way of sharing this resource? 2) How do feedback and cooperation improve resource utilization?

Biography : Dr. David Tse received his B.A.Sc. degree in systems design engineering from the University of Waterloo, Canada in 1989, and his M.S. and Ph.D. degrees in Electrical Engineering from Massachusetts Institute of Technology in 1991 and 1994 respectively. From 1994 to 1995, he was a postdoctoral member of the technical staff at A.T & T Bell Laboratories. Since 1995, he has been at the Department of Electrical Engineering and Computer Sciences at the University of California - Berkeley, where he is currently a Professor. He received a 1967 NSERC 4-year graduate fellowship from the government of Canada in 1989, a NSF CAREER award in 1998, the Best Paper Awards at the Infocom 1998 and Infocom 2001 conferences, the Erlang Prize in 2000 from the INFORMS Applied Probability Society, the IEEE Communications and Information Theory Society Joint Paper award in 2001, the Information Theory Society Paper Award in 2003, and the 2009 Frederick Emmons Terman award from the American Society for Engineering Education. He has given plenary talks at international conferences such as ICASSP in 2006, MobiCom in 2007, CISS in 2008, and ISIT in 2009. He was the Technical Program co-chair of the International Symposium on Information Theory in 2004, and an Associate Editor of the IEEE Transactions on Information Theory from 2001 to 2003. He is a co-author, with Pramod Viswanath, of the text "Fundamentals of Wireless Communication", which has been used in over 60 institutions around the world.
