Second-order statistics of SC macrodiversity system operating over Gamma shadowed Nakagami-m fading channels

Abstract

This paper derives the second-order statistics of SC (selection combining) macrodiversity operating over the Gamma shadowed Nakagami-m fading channels. Macrodiversity system of SC type consists of two microdiversity systems and selection (switching) is based on their output signal power values. Each microdiversity system is of MRC (maximal ratio combining) type with arbitrary number of branches in the presence of correlative Nakagami-m fading. We have derived the infinite-series expressions for LCR (level crossing rate) and AFD (average fading duration) at the output of this system. Numerical results are also presented in order to show the influence of various parameters such as number of the diversity branches at the microcmbiners, fading severity and level of correlation between those branches on the system's statistics, and then compared to the previously published results from this area.
