In this paper, we consider an optimal power allocation scheme for Rayleigh fading channels in cognitive relay networks considering both total transmit power and average interference power constraints. We derive the optimal power allocation scheme between the cognitive source and relay aiming at minimizing the bit error rate of cognitive system by applying convex optimization method. Simulation results indicate that the proposed scheme outperforms average power allocation scheme when the relay is located at different positions.
