题目：Training Sequence Design for Discriminatory Channel Estimation in Wireless MIMO Systems

（无线MIMO系统差异信道估计中的训练序列设计）

报告人：Chong-Yung Chi (祁忠勇)教授

Abstract:

This talk presents a training-based channel estimation scheme for achieving quality-of-service discrimination between legitimate and unauthorized receivers in wireless multiple-input multiple-output (MIMO) channels. This scheme has applications ranging from user discrimination in wireless TV broadcast systems to the prevention of eavesdropping in secret communications. The key idea is to exploit the channel estimate fed back from the LR at the beginning of each stage to enable the judicious use of artificial noise (AN) in the training signal. Specifically, with knowledge of the LR’s channel, AN can be properly superimposed with the training data to degrade the UR’s channel without causing strong interference on the LR.

Biography

Chong-Yung Chi (S’83-M’83-SM’89) received the Ph.D. degree in Electrical Engineering from the University of Southern California in 1983. From 1983 to 1988, he was with the Jet Propulsion Laboratory, Pasadena, California. He has been a Professor with the Department of Electrical Engineering since 1989 and the Institute of Communications Engineering (ICE) since 1999 (also the Chairman of ICE for 2002-2005), National Tsing Hua University, Hsinchu, Taiwan. His current research interests include signal processing for wireless communications, convex analysis and optimization for blind source separation, biomedical imaging and hyperspectral imaging.

Dr. Chi is a senior member of IEEE. He was an Associate Editor of IEEE Trans. Signal Processing (5/2001-4/2006), IEEE Trans. Circuits and Systems II (1/2006-12/2007), and a member of Editorial Board of EURASIP Signal Processing Journal (6/2005-5/2008), and an editor (7/2003-12/2005) as well as a Guest Editor (2006) of EURASIP Journal on Applied Signal Processing. Currently, he is an Associate Editor of IEEE Signal Processing Letters and IEEE Trans. Circuits and Systems I, and a member of IEEE Signal Processing Committee on Signal Processing Theory and Methods.
