Performance of SIR-based triple selection combining over correlated weibull channel

The performance analysis of a multi-branch selection combiner (SC) based on the signal to interference ratio (SIR) over exponentially correlated Weibull fading channels is main contribution of this paper. SIR based selection diversity is a very efficient technique that reduces fading and interference influence. In case of the desired and interfering signal envelopes are the exponentially correlated Weibull random variables, very useful expressions are obtained.
