On the performance of dual-hop cooperative system over Mixture Gamma fading channels
Weijun Cheng · 2013
In this paper, we present the end-to-end performance of a dual-hop cooperative system over independent non-identical composite Nakagami-lognormal (NL) fading channels using Mixture Gamma (MG) distribution. Novel closed-form expressions for the Probability density function (PDF) and the Moment-generation function (MGF) of the end-to-end Signal-to-noise ratio (SNR) are derived. Moreover, the average Symbol error rate (SER) and outage probability of the dual-hop cooperative system are found based on the above new expressions, respectively. Numerical and simulation results are shown to verify the accuracy of the analytical results.
