MGF-based performance analysis of selection diversity with switching constraints in nakagami fading

This paper focuses on the performance evaluation of selection combining (SC) diversity with switching constraints over independent non-identically distributed (i.n.i.d.) Nakagami-m fading channels. New closed-form expressions for the moment generating function (MGF) of the SC output signal-to-noise ratio (SNR) in Nakagami-m fading channels, as a function of channel decorrelation, have been obtained. These expressions have been the starting point to derive performance measures like average combined SNR, outage probability, and average bit error probability of various modulation schemes
