Abstract

Capitalizing on the Moschopoulos single gamma series representation of the probability density function (pdf) of the sum of gamma variates, we provide a pdf-based approach for the performance analysis of maximal-ratio combining and postdetection equal-gain combining diversity techniques as well as cochannel interference of cellular mobile radio systems over Nakagami-fading channels with arbitrary parameters. Aside from putting under the same umbrella many of the past results obtained via characteristic function (CF) or moment generating function (MGF)-based approaches, the proposed also allows the derivation of additional performance measures, which are harder to analyze via CF or MGF-based approaches.
