一类衰落信道下平均高斯差错概率的统一分析

Unified Analysis of the Average Gaussian Error Probability for a Class of Fading Channels

Jose F. Paris

摘要:

本文着重分析了在一定衰落信道中的平均高斯差错概率,即我们感兴趣的是E[Q((p γ)^(1/2))],其中Q(.)是高斯Q函数,p是正实数,γ是非负随机变量。本文给出了平均高斯误差概率的统一分析,导出了适用于广泛衰落信道的Lauricella FD^(n)函数的简洁表达式,并讨论了该表达式与最近文献中出现的这类表达式的关系。作为我们推导的中间步骤,我们还得到了同一类衰落信道的中断概率的紧凑表达式。最后,我们展示了这种统一分析如何使我们获得新颖的性能分析结果。

英文摘要:

This paper focuses on the analysis of average Gaussian error probabilities in certain fading channels, i.e. we are interested in E[Q((p γ)^(1/2))] where Q(.) is the Gaussian Q-function, p is a positive real number and γ is a nonnegative random variable. We present a unified analysis of the average Gaussian error probability, derive a compact expression in terms of the Lauricella FD^(n) function that is applicable to a broad class of fading channels, and discuss the relation of this expression and expressions of this type recently appeared in literature. As an intermediate step in our derivations, we also obtain a compact expression for the outage probability of the same class of fading channels. Finally, we show how this unified analysis allows us to obtain novel performance analytical results.
