The end-to-end performance of multibranch dual-hop wireless communication systems with nonregenerative relays and Equal Gain Combiner (EGC) at the destination over independent Nakagami-m fading channels is studied. The authors present new closed form expressions for Probability Distribution Function (PDF) and Cumulative Distribution Function (CDF) of end-to-end Signal to Noise Ratio (SNR) per branch in terms of Meijer's G function. From these results, analytical formulae for the moments of the output SNR, the average overall SNR, the amount of fading, and the spectral efficiency are also obtained in closed form.
