Abstract
In this paper, we present unified analytical expressions for the average bit error rate (BER) and the average channel capacity of single-branch receivers operating over generalized fading channels. More specifically, novel closed-form expressions for the average BER and the average channel capacity over generalized $\eta{-}\mu$ fading channels in terms of the bivariate Fox's H- function/Meijer's G-function are derived. The influence of the fading parameters $\eta$ and $\mu$ on the system performance is analyzed and discussed through representative numerical examples. The correctness of our derivations is validated by means of Monte-Carlo simulations. In addition, our analytical results are in excellent agreement with the results that have been previously reported in literature.
