Performance analysis of system with L-branch selection combining over correlated Weibull fading channels in the presence of cochannel interference

In this paper, the performance of L‐branch selection combining receiver over correlated Weibull fading channels in the presence of correlated Weibull‐distributed cochannel interference is analyzed. Closed‐form expressions for probability density function and cumulative distribution function of the signal‐to‐interference ratio at the output of the selection combining receiver present main contribution of this paper. Numerical results are also presented to show the effects of various parameters as the fading severity, correlation and number of branches on outage probability.

This paper analyzes the outage performance of L‐branch SC receiver over correlated Weibull fading channels in the presence of correlated Weibull‐distributed co‐channel interference. In order to carry out this analysis, closed‐form expression for the outage probability of considered system is derived. Presented numerical results show the effects of various parameters as the fading severity, correlation and number of branch on the outage probability. Copyright © 2009 John Wiley & Sons, Ltd.
