On the selection combining over correlated α-µ fading channels [articol]

Abstract

In this paper, system performances of selection combining and correlated α-µ (Generalized Gamma) fading channels are analyzed. Fading between the diversity branches is correlated and distributed with α-µ distribution.Very useful closed-form expressions are obtained for the output signal’s probability density function (PDF) and cumulative distribution function (CDF). The main contribution of this analysis for dualbranch signal combiner, is that it has been done for general case of α-µ (Generalized Gamma) distribution, which includes as special cases important other distributions such as Weibull and Nakagami-m (therefore, the One-Sided Gaussian and Rayleigh are also special cases of it), so our analysis has high level of generality.
