 +An I-MMSE Perspective to the Capacity of the MIMO Gaussian Wiretap Channel

 +Abstract: The fundamental relationship between information theory and
 +estimation theory in the Gaussian channel, is used for an alternative
 +derivation of the secrecy capacity of the multiple-input multiple-output
 +(MIMO) Gaussian wiretap channel, under a power-covariance constraint.
 +This approach yields closed form expressions in contrast to non-convex
 +optimization based formulas provided by the standard different
 +approaches (Khisti-Wornell,​ Oggier-Hassibi,​ Liu-Shamai). Furthermore,​
 +the input covariance matrix required in order to attain the capacity is
 +specified, and the current technique provides also some insight into the
 +concept of enhancement,​ and alternative expressions applied to this
 +problem by Liu-Shamai. An alternative expression for the secrecy
 +capacity of the MIMO Gaussian wiretap channel by Liu-Liu-Poor-Shamai is
 +also examined via the information-estimation perspective. A short
 +outlook will conclude the talk.
 +The talk is based on a joint work with R. Bustin, Technion, R. Liu and
 +V. Poor, Princeton University.
 +Biography: Shlomo Shamai (Shitz) (S'​80–M'​82–SM'​89–F'​94) 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 the Communications Research
 +Labs in the capacity of a Senior Research Engineer. Since 1986 he is
 +with the Department of Electrical Engineering,​ Technion—Israel Institute
 +of Technology, where he is now the William Fondiller Professor of
 +Telecommunications. His research interests encompass a wide spectrum of
 +topics in information theory and statistical communications. He is
 +especially interested in theoretical limits in communication with
 +practical constraints,​ multi-user information theory and spread spectrum
 +systems, multiple-input-multiple-output communications systems,
 +information theoretic models for wireless networks and systems,
 +information theoretic aspects of magnetic recording, channel coding,
 +combined modulation and coding, turbo codes and LDPC, in channel,
 +source, and combined source-channel applications,​ iterative detection
 +and decoding algorithms, coherent and noncoherent detection and
 +information theoretic aspects of digital communication in optical
 +channels. Dr. Shamai (Shitz) is a member of the Union Radio Scientifique
 +Internationale (URSI). He is the recipient of the 1999 van der Pol Gold
 +Medal of URSI, and a co-recipient of the 2000 IEEE Donald G. Fink Prize
 +Paper Award, the 2003, and the 2004 Joint IT/COM Societies Paper Award,
 +and the 2007 Information Theory Society Paper Award. He is also the
 +recipient of the 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 also serves on the Board of
 +Governors of the Information Theory Society.
