Outage Probability of Two Relay Systems with Two Sections on Selection Combining in the Presence of κ-μ Short Term Fading
Authors: , , , , ,
Abstract: Two wireless relay communication systems with two sections on selection combining (SC) are considered in this paper. Received signal in sections experiences κ-μ small scale fading. Signal envelope at output of relay systems can be evaluated as product of signal envelopes in sections. Therefore, probability density function (PDF) and cumulative distribution function (CDF) at output of relay system are calculated. SC receiver selects relay system with higher signal envelope. Thus, PDF and CDF of SC receiver signal envelope are calculated by solving integrals in the closed forms by using sums and Bessel function of the second kind. Then, they are graphically presented. The influence of Rician factors of κ-μ short term fading in sections and κ-μ short term fading severity parameters on the outage probability of considered relay system is analyzed and discussed. These results serve to designers of wireless systems to choose optimal system parameters in appropriate fading environment.
