Space-Time Coding/Modulation for Multiple Antenna Systems

Abstract: It has been commonly recognized that multiple transmit and multiple receive antennas can be used to significantly improve the channel capacity over a wireless fading channel. Similar to single antenna systems, to achieve a channel capacity, coding and modulation, i.e., space-time coding and modulation, is critical. In this talk, we will introduce state of the art and some of my recent research results on space-time coding techniques inlcuding unitary space-time designs, orthogonal space-time codes from orthogonal designs, and lattice based space-time codes.

Speaker:  Dr. Xiang-Gen Xia is a Professor of Electrical and Computer Engineering at the University of Delaware, Newark, Delaware. He received his Ph.D. degree in Electrical Engineering from the University of Southern California, Los Angeles, in 1992. His current research interests include space-time coding, MIMO and OFDM systems, and SAR and ISAR imaging. Dr. Xia has over 100 refereed journal articles published, and 6 U.S. patents awarded. He is the author of the book Modulated Coding for Intersymbol Interference Channels (New York, Marcel Dekker, 2000). He is currently an Associate Editor of the IEEE Transactions on Mobile Computing, the IEEE Signal Processing Letters, the International Journal of Signal Processing, and the EURASIP Journal of Applied Signal Processing. He was a guest editor of Space-Time Coding and Its Applications in the EURASIP Journal of Applied Signal Processing in 2002. He served as an Associate Editor of the IEEE Transactions on Signal Processing during 1996 to 2003. He is also a Member of the Signal Processing for Communications Technical Committee and the Sensor Array and Multichannel (SAM) Technical Committee in the IEEE Signal Processing Society.
