SUMMARYIn this paper, a numerical approach to the performance analysis of a signal-to-interference-based selection combining receiver, operating over a Rician multipath-fading environment, in the presence of multiple Nakagami-m cochannel interferers is provided. Closed form expressions are obtained for the first-order and second-order statistical measures, that is, the probability density function, cumulative distribution function, and average level-crossing rate of the received signal. Further, the aforementioned results are used for an efficient evaluation of other performance measures, such are outage probability and average fade duration. A graphical representation of the obtained numerical results is also provided in order to present and discuss the influence of transmission parameters on the studied performance measures.

Wireless mobile macrodiversity (MaD) radio system with switch and stay (SSC) receiver and two microdiversity (MiD) selection combining (SC) branches operating over Gamma shadowed Kappa-Mu (k-µ) multipath fading environment is considered. Novel, one-folded integral expression for average level crossing rate (LCR) of MaD SSC receiver output signal envelope is obtained. Numerical results of the proposed model are presented and discussed in relation to the system model parameters.
