Performance analysis in the context of selection diversity in non-identically distributed Weibull fading channels

In this paper, some analytical results for selection diversity over Weibull fading channels are presented. In particular, an analytical expression for the probability density function (pdf) of the maximum of a set of independent but not necessarily identically distributed (i.n.d.) Weibull random variables is derived. Expressions for the corresponding cumulative distribution function (cdf), moment generating function (MGF), and r-th moment are also obtained. The usefulness of the results is illustrated by application to the evaluation of outage probabilities.
