Abstract

This paper presents a study on the outage performance analysis of basic receive diversity combining schemes in terms of outage probability and average outage duration over Nakagami-0.5 fading channels. Recent attention has been given to Nakagami-0.5 fading channel as a special case of Nakakgami-m fading channel with m = 0.5 and as a worst-case (severe) fading scenario. Closed-form expressions for outage probability and average outage duration are derived for selection combining (SC), equal gain combining (EGC) and maximal-ratio combining (MRC) diversity schemes. The expressions derived are numerically evaluated to study the effect of diversity order and multipath intensity profile (MIP) on the system performance.
