Cognitive Relay Networks With Multiple Primary Transceivers Under Spectrum-Sharing

The authors examine the impact of multiple Primary Transmitters and Receivers (PU-TxRx) on the outage performance of cognitive decode-and-forward relay networks. In such a joint relaying/spectrum-sharing arrangement, they address fundamental questions concerning three key power constraints: maximum transmit power at the Secondary Transmitter (SU-Tx), peak interference power at the Primary Receivers (PU-Rx), and interference power at SU-Rx caused by the Primary Transmitter (PU-Tx). Their answers to these are given in new analytical expressions for the exact and asymptotic outage probability of the secondary relay network.
