We propose a cooperative spectrum sharing strategy in which the secondary system can access to the licensed spectrum of the primary system if it can help the primary system achieve the target rate. Specifically, the secondary system acts as a decode-and-forward relay for the primary system by splitting a fraction of its transmission bandwidth to help forward primary signal. It uses the remaining bandwidth...
In this paper, we propose an anti-interference cooperative spectrum sharing strategy in cognitive two-phase full-duplex relaying networks, in which the secondary system acts as a decode-and-forward relay to assist the primary system achieve the target transmission rate. As a reward, the secondary system can gain access to the licensed primary spectrum to transmit its own signal in both two phases...
