BEP comparison for dual SC systems using different decision algorithms in the presence of interference

Selection combining (SC) is one of the most efficient technique for mitigating deleterious effects of fading and cochannel interference in wireless communication systems. In this paper, bit error probability (BEP) performance of dual selection diversity system, which applies desired signal power algorithm, over correlated Rician fading channels in the presence of cochannel interference (CCI) is analyzed. Actually, the formula for the average BEP of considered diversity system is derived in the analytical form. Numerical results are presented to show the effects of various parameters such as the fading severity and level of correlation. Moreover, they are used to compare error performance of considered SC systems applying different decision algorithms.
