In this chapter, the authors present the performance of multi-antenna selective combining decode-and-
forward (SC-DF) relay networks over independent and identically distributed (i.i.d) Nakagami-m fading
channels. 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 character-
istics. After that, the authors formulate the outage probability problem, optimize it with an approximated
problem, and then solve it analytically. Finally, for comparison with analytical formulas, the authors
perform some Monte-Carlo simulations
