Second order statistics of selection macro-diversity system operating over gamma shadowed Ricean fading channels

Infinite-series expressions for the second-order statistical measures of a macro-diversity structure operating over the Gamma shadowed Ricean fading channels are provided in this paper. MRC (Maximal Ratio Combining) combining at each base station (micro-diversity), and selection combining (SC), based on output signal power values, between base stations (macro-diversity) are considered. In the paper some numerical results for Level crossing rate (LCR) and Average Fading Duration (AFD) are presented, in order to investigate the influence of various parameters such as shadowing, fading severity and number of the diversity branches at the micro-combiners on these measurements.
