论文摘要
在本文中，提出了一种新型的伽马阴影两射线（GS-TWDP）复合褪色模型。该模型旨在在以毫米波（MMWave）频率工作的新兴无线网络中进行建模，并作为TWDP分布的组合获得，用于描述多径效应和伽马分布，以模拟由于阴影而建模的变化。衍生精确的概率密度函数（PDF）后，获得了累积分布函数（CDF）和力矩生成函数（MGF）表达式。通过将分析获得的结果与在28 GHz测量并在文献中报告的结果进行比较，可以验证所提出的模型。然后，通过使用Chernoff和Chiani近似值，用于研究GS-TWDP参数和系统性能之间的关系，并用于研究两个上限平均符号误差概率（ASEP）表达式的表达式（ASEP）表达式。所有结果均通过蒙特卡洛模拟验证。
In this paper, a novel gamma-shadowed two-ray with diffuse power (GS-TWDP) composite fading model is proposed. The model is intended for modeling propagation in the emerging wireless networks working at millimeter wave (mmWave) frequencies, and is obtained as a combination of TWDP distribution for description of multipath effects and gamma distribution for modeling variations due to shadowing. After derivation of the exact probability density function (PDF), cumulative distribution function (CDF) and moment generating functions (MGF) expressions are obtained. Proposed model is verified by comparing the analytically obtained results with those measured at 28 GHz and reported in literature. Two upper bound average symbol error probability (ASEP) expressions are then derived for M-ary rectangular quadrature amplitude modulation (RQAM) by employing Chernoff and Chiani approximations of Gaussian Q-function, and are used to investigate relationship between GS-TWDP parameters and system performance. All the results are verified by Monte-Carlo simulation.
