摘要

本文介绍了一种分析任意相关三元威布尔分布的分析框架。对于这种分布,导出了联合概率密度函数、累积分布函数(CDF)和矩的无穷级数表示。研究了分布的两种特殊相关情况:指数型和常数型。这些级数表示易于应用于在威布尔相关衰落环境下工作的三支路选择组合(SC)接收机的性能分析,并推导出中断概率。本文提出的数学分析与各种数值结果相辅相成,显示了衰落严重程度、相关性和功率衰减因子的影响

The Trivariate Weibull Distribution with Arbitrary Correlation
In this paper an analytical framework for analyzing the arbitrarily correlated trivariate Weibull distribution is introduced. For this distribution infinite series representations for the joint probability density function, the cumulative distribution function (CDF) and the moments are derived. Two special correlation cases of the distribution are studied: the exponential and the constant. These series representations are readily applicable to the performance analysis of a 3-branch selection combining (SC) receiver operating in a Weibull correlation fading environment and the outage probability is derived. The proposed mathematical analysis is complemented by various numerical results, showing the effects of fading severity, correlation and the power decay factor
