Performance Analysis of SIR-Based Triple Selection Diversity Over CorrelatedWeibull Fading Channels

In this paper, closed-form expressions for the probability density function (PDF) and cumulative distribution function (CDF) of the signal-to-interference ratio (SIR) at the output of triple selection combining (SC) receiver over correlated Weibull fading channels are obtained. These expressions are used to study important system performance criteria such as the outage probability, average bit error probability (ABEP) and average output SIR. Numerical results are also graphically presented showing the effect of various systems parameters such as the average input SIR, fading severity and level of correlation on the systems performance.
