SUMMARYIn 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.

Level crossing rate and average fade duration of signal envelope of selection diversity are numerically determined. Statistical characterization in fading and shadowing mobile radio communication enveronment are very useful and in this paper that is computed for Ricean fading channels with lognormal shadowing. The results are presented for independent identically distributed diversity branches when selection combining technique is used.
