Error-Rate Performance of Selection Combining over Generalized Correlated Weibull Fading Channels
Authors: ,
Abstract: Error-rate performance is studied for selection combining (SC) with arbitrary number of diversity branches over generalized correlatedWeibull fading channels. Using a transformation of cumulative distribution function of average branch signal-to-noise ratio (SNR), we present the exact error-rate expressions for coherent and non-coherent modulations in infinite series forms. In particular, we develop asymptotic symbol error rate expressions with closed-form which are valid at high SNR. Presented numerical examples show that taking the first several terms of the series based error-rate expression results in improved error-rate estimation compared to the asymptotic error-rate. These error-rate expressions which can be evaluated efficiently indicate some significant insights into the characteristics of SC over generalized correlated Weibull fading channels. The accuracy of the analytical results is validated by the simulation results.
