“…In [4], the authors analyzed the performance of MRC, equal gain combining (EGC), selection combining (SC) and switch and stay combining (SSC) diversity receivers operating over the composite K G fading channels. A novel analytical expression for the probability density function (PDF) of the sum of two correlated, dissimilar Nakagami-0.5 RVs was derived in [5], while the author in [6] derived the exact and approximate PDF and cumulative distribution function (CDF) of dual selection with MRC over nonidentical imperfect channel estimation.…”

Capitalizing on the recently proposed Fisher-Snedecor F composite fading model, in this letter, we investigate the sum of independent but not identically distributed (i.n.i.d.) Fisher-Snedecor F variates. First, a novel closed-form expression is derived for the moment generating function of the instantaneous signal-to-noise ratio. Based on this, the corresponding probability density function and cumulative distribution function of the sum of i.n.i.d. Fisher-Snedecor F variates are derived, which are subsequently employed in the analysis of multiple branch maximal-ratio combining (MRC). Specifically, we investigate the impact of multipath and shadowed fading on the outage probability and outage capacity of MRC based receivers. In addition, we derive exact closed-form expressions for the average bit error rate of coherent binary modulation schemes followed by an asymptotic analysis which provides further insights into the effect of the system parameters on the overall performance. Importantly, it is shown that the effect of multipath fading on the system performance is more pronounced than that of shadowing.

“…While tractable closed-form expressions exist for the performance measures of MRC diversity operating with input branches having equal powers (balanced case), simple closed-form expressions for the performance measures of MRC diversity operating with input branches having unequal powers (unbalanced case) are, in general, not known. While closed-form solutions for the outage probability of MRC diversity operating on Nakagami-0.5 channels were recently published in [3], these solutions are only for Nakagami-0.5 channels. The situation is illustrated in Table 1, where seven examples of popular books on digital wireless communications [4][5][6][7][8][9][10] give the known simple closed-form expression for the SNR probability density function (PDF) of MRC operating on balanced diversity branches in Rayleigh fading, but either (i) lack any tractable closed-form expression for the SNR density of MRC operating on unbalanced Rayleigh diversity branches at all, or (ii) only present a closed-form solution for the SNR density of MRC operating on unbalanced Rayleigh diversity branches with distinct (different) powers.…”
