Low-complexity timer-based multi-relay selection and sequential power allocation of cooperative cognitive radio networks for future Internet of things

International Journal of Distributed Sensor Networks, 2016
Cooperative cognitive radio networks use cooperative relays to forward signal from the source to the destination. In cooperative cognitive radio networks, the transmission power of each relay is limited by the interference constraint of the primary user ...

On the performance of full-duplex relaying with relay selection

Electronics Letters, 2010
A two-hop cooperative communication network with full-duplex relaying and relay selection is addressed. Closed-form expressions for average capacity and symbol error rate are derived in an independent and identically distributed Rayleigh fading environment.
