Abstract :
In this paper, the performance of the outage probability (OP) for cognitive dual-hop relay networks with amplify-and-forward (AF) relay under spectrum sharing constraints on primary user (PU) over independent and identically distributed (i.i.d.) Nakagami-m fading channels is investigated. An exact closed-form expression for the OP of the proposed system is derived under the peak interference power (Ip) at the primary user. The impact of the PU location on the OP performance is studied also.
