The Advanced Network Colloquium Series

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.
