Outage probability of dual-hop amplify-and-forward cognitive relay networks under interference power constraints over Nakagami-m fading channels

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 (I p ) at the primary user. The impact of the PU location on the OP performance is studied also.
