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

Abstract

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 <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</inf> on the system's performance is considered.
