Bit-error rate of binary digital modulation schemes in generalized gamma fading channels

Abstract

We derive a closed-form expression for the bit-error rate of binary digital modulation schemes in a generalized fading channel that is modeled by the three-parameter generalized gamma distribution. This distribution is very versatile and generalizes or accurately approximates many of the commonly used channel models for multipath, shadow, and composite fading. The result is expressed in terms of Meijer's G-function, which can be easily evaluated numerically.
