Complete analytical model of dual-hop relay system over ricean fading channels

In this paper we present a complete analytical model, including closed form expressions for probability density function (PDF), cumulative distribution function (CDF) and moment generating function (MGF) of total received SNR (signal-to-noise ratio) for dual hop amplify-and-forward relay transmission over non-identical Ricean fading channels. Furthermore, adequate 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.
