Performance analysis of linear diversity combining schemes on Nakagami-0.5 fading channels

Abstract

This paper presents the performance analysis of three linear diversity combining schemes in terms of outage probability (OP), level crossing rate (LCR) and average outage duration (AOD) over Nakagami-0.5 fading channels. Closed-form expressions for OP, LCR and AOD are derived for selection combining (SC), equal gain combining (EGC) and maximal-ratio combining (MRC) receive diversity schemes. The expressions derived are numerically evaluated to study the effect of diversity order and exponentially decaying multipath intensity profile (MIP) on the system performance.
