Optimal Power Allocation for Linear Dispersion Codes Over Correlated MIMO Channels with Channel State Feedback
— The design of spatio-temporal power allocation schemes is considered for space-time coding over spatially correlated multiple-input multiple-output (MIMO) channels. The focus i...

Lower Bounds on the Capacity Regions of the Relay Channel and the Cooperative Relay-Broadcast Channel with Non-Causal Side Infor
— In this work, coding for the relay channel (RC) and the cooperative relay broadcast channel (RBC) controlled by random parameters are studied. In the first channel, the RC, in...

Optimal Flow Distribution Among Multiple Channels with Unknown Capacities
Consider a simple network flow problem in which there are n channels directed from a source to a sink. The channel capacities are unknown and we wish to determine a feasible netwo...
