Performance analysis of dual hop relay link in Nakagami-m fading channel with interference at relay

In this paper we consider performance of a dual hop amplify-and-forward system, with co-channel interference at relay. We consider channel state information assisted system in Nakagami-m channel. The outage probability and the average bit error probability of the system are determined. The influence of the interference, as well as the influence of other system´s parameters, such as the fading parameter m and outage probability threshold γ_th on the system´s performance is considered.
