Old and New: an Information-Estimation Perspective

October 1, 2013
Davis Auditorium, CEPSR
Speaker: Shlomo Shamai, Professor, Dept. of Electrical Engineering, Technion


This talk is a subjective overview of selected topics in Information Theory, Communications, and Signal Processing presented from an information-estimation perspective. We will first review basic information-estimation (I-MMSE) relations and properties in Gaussian additive channels and then use this framework to address specific problems and results in:

  • nonlinear optimal filtering;
  • multi-terminal models that relate to broadcast, wiretap and interference channels, with highlights regarding novel aspects in interference alignment;
  • efficient codes for point-to-point, interference and relay channels.

A statistical physics view of I-MMSE related relations will be briefly mentioned, as well as other applications motivated by the I-MMSE paradigm. We will point out some new observations and results, emphasizing specific research challenges motivated by the information-estimation perspective. The presentation will conclude with an examination of general channels and network information-theoretic concepts.

Speaker Bio

Shlomo Shamai (Shitz) received the B.Sc., M.Sc., and Ph.D. degrees in electrical engineering from the Technion (Israel Institute of Technology) in 1975, 1981, and 1986 respectively. During 1975-1985, he was with Communications Research Labs in the capacity of a Senior Research Engineer. Since 1986, he has been with the Technion's Department of Electrical Engineering, where he is now a Technion Distinguished Professor and holds the William Fondiller Chair of Telecommunications. His research interests encompass a wide spectrum of topics in information theory and statistical communications.

Dr. Shamai (Shitz) is an IEEE Fellow, a member of the Israeli Academy of Sciences and Humanities, and a Foreign Associate of the US National Academy of Engineering. He is the recipient of the 2011 Claude E. Shannon Award. He has been awarded the 1999 van der Pol Gold Medal of the Union Radio Scientifique Internationale (URSI), and is a co-recipient of the 2000 IEEE Donald G. Fink Prize Paper Award, the 2003, and the 2004 joint IT/COM societies paper award, the 2007 IEEE Information Theory Society Paper Award, the 2009 European Commission FP7, Network of Excellence in Wireless Communications (NEWCOM++) Best Paper Award, and the 2010 Thomson Reuters Award for International Excellence in Scientific Research. He is also the recipient of 1985 Alon Grant for distinguished young scientists and the 2000 Technion Henry Taub Prize for Excellence in Research. He has served as Associate Editor for the Shannon Theory of the IEEE Transactions on Information Theory, and has also served twice on the Board of Governors of the Information Theory Society. He is a member of the Executive Editorial Board of the IEEE Transactions on Information Theory.
