Performance of selection combiner over Nakagami fading channel with Laplace cochannel interference

Abstract

Wireless communications channel is multipath propagation channel and its main drawback is fading that degrades system performance. Multipath fading effects can be mitigated by using diversity combing scheme at the receiver. Many diversity combining schemes were considered in the literature to study their performance in different multipath fading environments. Recently, N. C. Beaulieu considered generalized framework for performance analysis of selection combining diversity in Rayleigh fading channel by deriving expressions for average error rate. However, experimental measures shown that the Nakagami fading channel model is a good fit to different multi-path fading environments. Hence the performance analysis of selection diversity combining scheme in Nakagami fading channels with Laplace cochannel interference is presented in this paper by deriving the average error rate of binary phase shift keying signals.
