On the Simulation and Correlation Properties of TWDP Fading Process

Almir Maric, Pamela Njemcevic

AI总结:

本文提出一种TWDP衰落信道统计仿真器,用零均值随机正弦波模拟镜面分量、正弦波之和模拟漫散射分量,首次推导出正交分量及包络的相关函数,并通过仿真验证了其统计特性与理论一致。

摘要:

本文提出了一种新型统计仿真器,用于对双向漫散射功率(TWDP)衰落信道中的传播进行建模。该仿真器采用两个零均值随机正弦波来模拟镜面分量,同时使用正弦波之和来模拟漫散射分量。利用所开发的仿真器,首次在文献中推导出了经历TWDP衰落的信道的正交分量的自相关函数和互相关函数,以及复包络和平方包络的自相关函数。通过大量仿真对所提仿真器的统计特性进行了全面验证,仿真结果与理论结果高度吻合。

英文摘要:

This paper introduces a novel statistical simulator designed to model propagation in two-way diffuse power (TWDP) fading channels. The simulator employs two zero-mean stochastic sinusoids to simulate specular components, while a sum of sinusoids is used to model the diffuse one. Using the developed simulator, the autocorrelation and cross-correlation functions of the quadrature components, as well as the autocorrelation of the complex and squared envelope, are derived for the first time in literature for channels experiencing TWDP fading. The statistical properties of the proposed simulator are thoroughly validated through extensive simulations, which closely align with the theoretical results.
