In this study, the author investigates the outage performance of cognitive relay networks, in which the best relay is selected based on full and partial channel state information, respectively. The author derives exact closed-form expressions for both relay selection schemes, and study their asymptotic performance in terms of the diversity order based on the performance bound analysis. Simulation results are provided to confirm the accuracy of the analytical results, and highlight performance gains provided by the relay selection in cognitive radio networks.
