论文摘要
我们提出了一个复合无线褪色模型，包括基于波动的两射线（FTR）褪色和逆伽玛（IG）阴影的多径褪色和阴影。我们首先确定了FTR褪色模型的统计表征和性能评估的替代框架，该框架基于以下事实：FTR褪色分布可以描述为具有连续变化的参数KR的基础Rician Shadowed（RS）分布（镜面与差异成分的比率不断变化）。我们证明，这种新的公式允许获得FTR模型的广义力矩生成函数（GMGF）的闭合形式表达，从中可以以封闭形式获得复合Ig/Ftr模型的PDF和CDF。通过Monte Carlo模拟分析和验证Ig/FTR模型的确切和渐近中断概率。
We present a composite wireless fading model encompassing multipath fading and shadowing based on fluctuating two-ray (FTR) fading and inverse gamma (IG) shadowing. We first determine an alternative framework for the statistical characterization and performance evaluation of the FTR fading model, which is based on the fact that the FTR fading distribution can be described as an underlying Rician Shadowed (RS) distribution with continuously varying parameter Kr (ratio of specular to diffuse components). We demonstrate that this new formulation permits to obtain a closed-form expression of the generalized moment generating function (GMGF) of the FTR model, from which the PDF and CDF of the composite IG/FTR model can be obtained in closed-form. The exact and asymptotic outage probability of the IG/FTR model are analyzed and verified by Monte Carlo simulations.
