|Speaker:||Dr. Hamid Jafarkhani, University of California, Irvine|
In this talk, first, we consider recent advances in space-time coding. Then, we present the application of distributed space-time codes in wireless adhoc and relay networks. The talk continues with a discussion of open-loop and closed-loop MIMO systems. Especially, we propose the combination of space-time coding and beamforming for systems with limited feedback. We show how one can model a MIMO system with limited feedback as a source coding problem. As a result, many known source coding solutions are utilized in closed-loop systems.
Hamid Jafarkhani received the B.S. degree in electronics from Tehran University in 1989 and the M.S. and Ph.D. degrees both in electrical engineering from the University of Maryland at College Park in 1994 and 1997, respectively. He joined AT&T Labs-Research in 1997. Currently, he is Professor in the Department of Electrical Engineering & Computer Science at the University of California, Irvine where he is also the Deputy Director of Center for Pervasive Communications & Computing.
