Performance analyzes of dual-hop relay system over Ricean fading channels

In this paper we present analytical model for performance evaluation of dual hop amplify-and-forward relay transmission over non-identical Ricean fading channels on both hops. Probability density function (PDF) and moment generating function (MGF) of total received SNR (signal-to-noise ratio) are presented as fast converging sum. Furthermore, adequate semi-closed form expressions for average bit error rate (BER) and outage probability (OP) are derived. Numerical and simulation results confirm the validity of the proposed analytical model. Additionally, we analyzed the impact of unbalanced SNRs of the two hops on the error performance of the considered relay system.
