The end-to-end performance of dual-hop wireless communication system with fixed gain relays is investigated over independent non-identical composite Nakagami-lognormal fading channels using mixture gamma distribution. Novel closed-form expressions for the outage probability, the average symbol error rate and the nth moments of end-to-end signal to noise ratio (SNR) for the considered system are derived, respectively. Numerical and simulation results are shown and discussed to verify the accuracy of the analytical results under different scenarios, such as varying average SNR, fading parameters per hop, and the location of relaying nodes.
