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.

Nakagami-0.5衰落信道下线性分集组合方案的性能分析
本文从中断概率(OP)、平交率(LCR)和平均中断时间(AOD)三个方面分析了三种线性分集组合方案在Nakagami-0.5衰落信道上的性能。针对选择组合(SC)、等增益组合(EGC)和最大比组合(MRC)的分集方案,导出了OP、LCR和AOD的封闭表达式。数值分析了分集阶数和指数衰减多径强度分布(MIP)对系统性能的影响。
