Seminar: Distributed MU-MIMO with Over-The-Air Synchronization

Long after MIMO communication has been proposed as a viable path around the rate limitations of point-to-point communication, achieving its most general forms remains an elusive goal. In today's Internet, the scenario of interest is realizing wireless data transmission at high data rates over the last hop, serving simultaneously multiple users from different access point locations. Current multiuser signal multiplexing schemes require that different access points coordinate their transmissions to the symbol and phase level, thus requiring the realization of a distributed MIMO system. In this talk we describe the techniques used in creating such a system using over-the-air synchronization and present our experimental results. Horia Vlad Balan has obtained BSc degrees in Electrical Engineering and Computer Science and Mathematics in 2004 and a MSc degree in Computer Science in 2006 from Jacobs University Bremen. He is currently pursuing a PhD degree in Electrical Engineering at the University of Southern California. His interests are in the areas of in wireless networks, operating systems and software-radio based experimentation. His most recent topic is the practical realization of distributed MIMO systems capable of achieving full spatial multiplexing, which he has prototyped using software radio.
