SC Diversity Receiver over Rician Correlated Fading: Average SIR and Average SEP

Abstract

Ascertaining the importance of the dual selection combining (SC) receiver and ability of Rician model to describe fading in wireless communications, we derive infinity-series representation for the probability density function (PDF) of output signal-to-interference ratio (SIR) at dual SC receiver over correlated Rician fading channels in the presence of correlated Rayleigh distributed cochannel interference (CCI). This expression is used to study important wireless system performance criteria, such as average output signal-to-interference ratio (ASIR) and average symbol error probability (ASEP) for several modulation schemes. Numerical results presented in this paper point out effects of correlation and fading severity on the system performance.
