T13: Multiple Antenna Systems from Optimum Combining to MIMO

Presenters: Marco Chiani, University of Bologna
Moe Win, Massachusetts Institute of Technology


Multiple antenna systems can exploit the spatial resource to mitigate multipath, to reduce multiuser interference, and to increase spectral efficiency. Applications include wireless cellular systems, high-speed wireless LAN, WiMAX as well as energy-constrained multi nodes wireless systems. This tutorial provides the basic principles and applications of multiple antenna systems, including MIMO and distributed MIMO, and their analysis based on random matrix theory. Recent results on the effect of space and time correlation on the capacity of MIMO systems will be discussed. Then we present practical solutions for MIMO systems, and their performance analysis. Finally, we illustrate some applications of multiple antenna systems and MIMO in cellular systems, wireless LAN, WiMAX, and cooperative diversity for energy constrained wireless sensor networks. It will cover relevant topics including:

• Introduction to multiple antenna systems: diversity, interference, spectral efficiency
• Basic concepts in random matrices theory
• Theoretical limits: the capacity of MIMO systems
• Effects of space and time correlation on MIMO capacity
• Effects of interference: capacity of MIMO in a multiuser scenario
• Distributed MIMO
• Optimum combining to counteract multipath and interference
• MIMO-MMSE: architecture and analytical performance evaluation
• Application of multiple antenna to cellular systems, wireless LAN, WiMAX, and
energy-constrained wireless networks


Marco Chiani – Wireless Communications Laboratory, University of Bologna, Italy Marco Chiani was born in Rimini, Italy, in April 1964. He received the Dr. Ing. degree (magna cum laude) in Electronic Engineering and the Ph.D. degree in Electronic and Computer Science from the University of Bologna in 1989 and 1993, respectively. Dr. Chiani is a Full Professor at the II Engineering Faculty, University of Bologna, Italy, where he is the Chair in Telecommunication. During the summer of 2001 he was a Visiting Scientist at AT&T Research Laboratories in Middletown, NJ. He is a frequent visitor at the Massachusetts Institute of Technology (MIT), where he presently holds a Research Affiliate appointment. Dr. Chiani’s research interests include wireless communication systems, MIMO systems, wireless multimedia, low density parity check codes (LDPCC) and UWB. Under the European research program PROMETHEUS he has worked on short-range millimeter wave communication systems for Advanced Road Transport Telematics. He is also leading the research unit of CNIT/University of Bologna on Joint Source and Channel Coding for wireless video (IST FP6, project Phoenix) and is a consultant to the European Space Agency (ESA-ESOC) for the design and evaluation of error correcting codes based on LDPCC for space CCSDS applications. Dr. Chiani is actively involved in various communications research activities worldwide. He is the past chair (2002-2004) of the Radio Communications Committee of the IEEE Communication Society and the current Editor of Wireless Communication for the IEEE TRANSACTIONS ON COMMUNICATIONS. Dr. Chiani has chaired, organized sessions and served on the Technical Program Committees at several IEEE International Conferences. He was Co-Chair of the Wireless Communications Symposium at ICC 2004. In January 2006 he received the ICNEWS award “For Fundamental Contributions to the Theory and Practice of Wireless Communications.”

Moe Win is an Associate Professor at the Laboratory for Information & Decision Systems (LIDS), Massachusetts Institute of Technology. Prior to joining LIDS, he spent 5 years at AT&T Research Laboratories and 7 years at the Jet Propulsion Laboratory. His main research interests are the application of mathematical and statistical theories to communication, detection, and estimation problems. Specific current research topics include measurement and modeling of timeˆvarying channels, design and analysis of multiple antenna systems, ultraˆwide bandwidth (UWB) communications systems, optical communications systems, and space communications systems.

Dr. Win has been involved actively in organizing and chairing a number of international conferences. He served as the chair (2004-2006) and secretary (2002-2004) for the Radio Communications Committee of the IEEE Communications Society. Dr. Win is currently an Editor for IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS. He served as Area Editor for Modulation and Signal Design (2003-2006), Editor for Wideband Wireless and Diversity (2003-2006), and Editor for Equalization and Diversity (1998-2003), all for the IEEE TRANSACTIONS ON COMMUNICATIONS. He served as a GuestˆEditor for the 2002 IEEE Journal on Selected Areas in Communications (Special Issue on UltraˆWideband Radio in Multiaccess Wireless Communications). He received the IEEE Antennas and Propagation Society Sergei A. Schelkunoff Transactions Prize Paper Award in 2003. In 2004, he received the Fulbright Fellowship, the Institute of Advanced Study Natural Sciences and Technology Fellowship, and the Presidential Early Career Award for Scientists and Engineers from the United States White House. He was honored with the 2006 IEEE Eric E. Sumner Award „for pioneering contributions to ultra-wide band communications science and technology.‰ Professor Win is an IEEE Distinguished Lecturer and elected Fellow of the IEEE, cited „for
contributions to wideband wireless transmission.
