摘　　要：本文详细讨论了无线移动通信系统中的信道性能及信道模犁的仿真方法，重点讲述了多径衰落信道的原理及其数学模型的构造，并给出了一个基于简单多径信道模型的QPSK系统性能的仿真结果，总结了不同参数的多径衰落对无线移动通信系统性能的影响。In this paper, channel performance and channel model simulation method were discussed in detail in the wireless communication system. Themultipath fading channel theory and mathematical models of the structure are the emphasis. And this paper gives a number of performance simulation results based on a simple channel model of the QPSK system, then summarized the system performance impacts which caused by the different parameters of the multipath fading communication.
