Space-Time Coding

A 2-Day Short Course

This course provides practicing engineers with the theoretical understanding and practical implementation techniques to apply modern channel coding to data transmission and reception with multiple antennas. Participants learn why space-time modem technology offers a large potential to support high-spectral efficiency in wireless data communications. Much of this potential has already been reached by many proposed modem architectures and yet there are still many open research questions. Participants are provided with an overview of the variety of proposed paradigms in space-time modems, and investigate the details of modulation and demodulation for these paradigms. Discussions include how to implement encoders and decoders, as well as how the different architectures relate to each other in terms of performance, complexity, and memory requirements.

Course Materials

Lecture notes are distributed on the first day of the course. The notes are for participants only and are not for sale.

Coordinator and Lecturer

Michael P. Fitz, PhD, Professor, Department of Electrical Engineering, Henry Samueli School of Engineering and Applied Science, UCLA. Since 1989, Dr. Fitz has been an academic pursuing research in wireless communications with over 100 patents granted, and journal and conference papers published. He has consulted numerous times in the area of physical layer wireless communications. His research group has implemented an experimental wide-area wireless packet data network. The physical layer architecture of this network is based heavily on his group’s theoretical research and has been implemented in a software-defined radio architecture. A current focus of this effort is on multiple antenna measurements and implementations of space-time coded systems. He has worked at Hughes and TRW in California as a communication system engineer, where his work focused on land mobile and satellite communications. Dr. Fitz was awarded the 2001 IEEE Communications Society Leonard G. Abraham Prize Paper Award in the Field of Communications Systems and is a member of the editorial board of the IEEE Transactions on Communications.

Lecturers

Hesham El Gamal, PhD, Assistant Professor, Electrical Engineering Department, Ohio State University, Columbus, Ohio. Dr. El Gamal has been with Ohio State University since January, 2001, where his research group is currently funded by the National Science Foundation ITR and CCR programs. His research interests include ad-hoc wireless networks, multiuser detection techniques, coding for fading channels with emphasis on space-time codes, and coding and signal processing over graphical models. He was previously a project manager in the Middle East Regional Office of Alcatel Telecom (1993-1996); research assistant, Department of Electrical and Computer Engineering, University of Maryland, College Park (1996-1999); senior member of the technical staff, Advanced Development Group, Hughes Network Systems, Germantown, Maryland (1999-2000); and a lecturer at the University of Maryland (Fall, 1999). He currently serves as an Associate Editor for Space-Time Coding and Spread Spectrum, IEEE Transactions on Communications.

Giuseppe Caire, PhD, Professor, Department of Mobile Communications, Institute Eurecom, Sophia-Antipolis, France. Professor Caire’s interests are focused on digital communications theory, information theory, coding theory, and multiuser communications, with particular focus on wireless terrestrial and satellite applications. He was a recipient of the AEI G. Someda Scholarship in 1991, the COTRAO Scholarship in 1996, and a CNR Scholarship in 1997. He was with the European Space Agency (ESTEC, Noordwijk, The Netherlands) in 1995; has been assistant professor in Telecommunications, Politecnico di Torino (1994-1998); and was associate editor for CDMA and Multiuser Detection, IEEE Transactions on Communications (1998-2001). Dr. Caire is currently Associate Editor for Communication Theory, IEEE Transactions on Information Theory; co-author of more than 30 papers in international journals and more than 80 in international conferences; and he is the author of three international patents with the European Space Agency.
