Abstract

Motivated by the importance of the Ricean statistical model in describing communication channels, in this paper we study the performance of a dual-hop amplify-and-forward relay transmission over non-identical Ricean fading channels. A complete analytical model for the performance evaluation of the analyzed system is presented. The probability density function, cumulative distribution function and moment generating function of the total received signal-to-noise ratio are derived in a form of rapidly converging infinite sum. Based on the derived expressions, we further proceed with the calculation of the outage probability and the average bit error rate performance of the system under study. 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.
