Abstract

This paper studies the performance of a dual-hop amplify-and-forward (AF) system where the source-relay and relay-destination channels experience Rayleigh and Rician fading, respectively. The relay node is corrupted by Rayleigh faded multiple co-channel interferences. Based on proposed system model, new closed-form expression for the average bit error rate (ABER), in the case of several modulation formats, is derived. Numerical results are performed in order to verify analytical approach.
