On the Average Bit Error Rate and Average Channel Capacity over Generalized Fading Channels

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 η-μ fading channels in terms of the bivariate Fox´s H-function/Meijer´s G-function are derived. The influence of the fading parameters η and μ 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.
