Generic form for average error probability of binary signals over fading channels

The authors present a generic form for the average bit error rate (BER) of coherent, differentially coherent, and noncoherent binary signals over fading channels. This generic form relies on an alternate representation of the incomplete gamma function and, for all the channel fading models under consideration, leads to an expression of the average BER involving a single finite-range integral of tabulated functions which can easily be computed numerically.
