下载后可任意编辑基于 MATLAB 的移动衰落信道仿真摘要：本文基于 MATLAB 对移动衰落信道进行仿真。重点利用 JAKES 法对瑞利信道进行了确定性模型仿真，对其功率谱密度和自相关函数进行了讨论。通过比较仿真模型与参考模型，说明了仿真模型的正确性。同时，仿真结果表明，仿真结果的特性主要取决于最大多普勒频移与谐波个数这两个参数。关键词： 瑞利信道；功率谱密度；自相关函数；JAKES 法；最大多普勒频移Mobile Fading Channel Simulation Based on MATLABAbstract: In this thesis, mobile fading channel is simulated based on MATLAB. It mainly focuses on the deterministic model simulation of Rayleigh channel using JAKES method, and its power spectral density and autocorrelation function are discussed. By comparing the simulation model with the reference model, it demonstrates the correctness of simulation models. At the same time, the simulation results indicate that the results are mainly depending on following two parameters: the maximum Doppler frequency shifts and the number of harmonic waves.Keywords: Rayleigh channel； power spectral density；autocorrelation function；Jakes method；maximum Doppler shift下载后可任意编辑目录 前言........................................................................................................1第一章 绪论...........................................................................................................................21.1 讨论背景及意义............................................................................................................21.2 讨论内容........................................................................................................................2第二章 无线信道的概念与特性.......................................................................................32.1 移动无线信道的概念....................................................................................................32.2 移动无线信道基本理论.............
