“…The selection combining diversity receiver with inputs operating over identical, independent Weibull multipath fading channel is considered next. Signal envelopes at inputs of a SC receiver are denoted with x 1 and x 2 , and the SC receiver output signal envelope is denoted with x. PDF of SC receiver output signal envelope is [16]:…”

In this paper, we consider wireless mobile radio communication system with macro diversity reception. Signal is subject to Weibull small scale fading and Gamma large scale fading resulting in system performance degradation. Receiver uses macro diversity selection combining (SC) technique in order to reduce the impact of long term fading effects, and two micro diversity SC branches are used to mitigate Weibull short term fading effects on system performance. Probability density function (PDF), and cumulative distribution function (CDF), as well as level crossing rate (LCR) and average fade duration (AFD) of the SC receiver output signal envelope are evaluated. The obtained expressions converge rapidly for all considered values of Weibull fading parameter and Gamma shadowing severity parameter. Mathematical results are studied in order to analyze the influence of Weibull fading parameter and Gamma shadowing severity parameter on statistical properties of the SC receiver output signal.

“…Hinging on the fact that selection combining (SC) diversity enjoys the lowest implementation complexity, the performance of macro-diversity and micro-diversity systems using SC were studied in [15], [16]. MRC gives the best performance of all the diversity techniques, and in [17], the performance of MRC receiver over Hoyt fading was studied.…”
