Abstract :
In this paper, we present the performance of multi-antenna selective combining decode-and-forward relay networks over independent but non-identical distributed Nakagami-m fading channels with imperfect channel estimation. The outage probability, moment generation function (MGF) and symbol error probability (SEP) are derived in closed-form using the signal to noise ratio (SNR) statistical characteristics. Lastly, to evaluate the accuracy of our analytical formulas, we carry out Monte-Carlo simulations.
