Message and State Cooperation in a Relay Channel When the Relay Has Strictly Causal State Information
—A state-dependent relay channel is studied in which strictly causal channel state information is available at the relay and no state information is available at the source and d...

A Cooperative Sensing Based Cognitive Relay Transmission Scheme Without a Dedicated Sensing Relay Channel in Cognitive Radio Net
—In this paper, we investigate a selective relay spectrum sensing and best relay data transmission (SRSS-BRDT) scheme for multiple-relay cognitive radio networks. Specifically, ...
