摘要

摘要: 该文提出了一种新的简单的产生满足任意自相关特性的瑞利波形的仿真模型，在此基础上得出无线信道中瑞利衰落波形的产生方法。该方法可以容易地产生多个相互独立的瑞利衰落波形，从而为研究各种频率分集无线通信系统提供了可能。仿真结果表明该模型能够有效地产生符合小尺度无线信道特征的瑞利衰落波形，满足自相关特性及平稳性的要求。

Abstract: In this paper, a novel and simple simulation model for the generation of Rayleigh waveforms with various autocorrelation properties is proposed. Based on this model, the method for generating the Rayleigh fading waveforms in wireless channels is given. By using the model, an arbitrary number of independent Rayleigh fading waveforms can be easily generated, which is of great importance for realistic performance assessments of the frequency-diversity wireless communication systems. Simulation results show that the model can effectively generate the Rayleigh waveforms with small-scale channel characteristics, which satisfy the autocorrelation property and stationary requirement.
