Cognitive Amplify-and-Forward Relay Networks Over Nakagami-M Fading

In this paper, the Outage Probability (OP) of dual-hop cognitive Amplify-and-Forward (AF) relay networks subject to independent non-identically distributed (i.n.i.d.) Nakagami-m fading is examined. The authors assume a spectrum-sharing environment, where two different strategies are proposed to determine the transmit powers of the secondary network. Specifically, the transmit power conditions of the proposed spectrum-sharing network are governed by either the combined power constraint of the interference on the primary network and the maximum transmission power at the secondary network or the single power constraint of the interference on the primary network.
