Performance analysis of dual-branch selection combining technique over the generalized Alpha-Mu fading channels

Inspired by the low-difficulty of implementing a dual-branch selection combining (SC) technique, this research paper presents approximate closed form expressions for bit error rate (BER) M-ary phase shift keying (M-PSK) considering SC technique. In particular, BER expression is derived over independent and identically distributed (i.i.d) alpha - mu fading channels based on use Meijer’s G-function. The presented mathematical formulas can be modified to study performance different types including Weibull, exponential, Nakagami-m, Gamma, Rayleigh channels. This achieved updating parameters propagation medium nonlinearity (alpha) number multipath clusters (mu). addition, provides numerical results that demonstrate close match in simulation findings terms BER. Specifically, very total using range signal noise ratio (SNR) levels various selections parameters. obtained M-PSK technique novel, new, has never been published literature before.
