Performance analysis of selective combining decode-and-forward relay networks over Nakagami-n and Nakagami-q fading channels

In this paper, we present the performance of selective combining decode-and-forward relay networks in independent and non-identically distributed Nakagami-n and Nakagami-q fading channels by using the best-worse and the decoding-set approaches. The outage probability, moment generation function, symbol error probability and average channel capacity are derived in closed-form using the signal to noise ratio SNR statistical characteristics. After that, we analyze the outage probability at high SNRs, and then, we optimize it. Beside the optimum method, we have proposed a sub-optimum adaptive method. Also, we derive the outage probability for the selection-combining case with the direct link between the source and the destination. Finally, for comparison with analytical formulas, we perform some Monte-Carlo simulations. Copyright © 2012 John Wiley & Sons, Ltd.
