摘　　要：为解决《通信原理》课程的硬件实验系统存在局限性导致部分实验不能做的问题,采用MATLAB软件仿真的方法,通过两个实例——MPSK系统误码率测试实验和各种数字通信信号功率谱密度分析实验,解决了硬件信号源的随机性产生并弥补了实验系统缺乏滤波器的缺陷,从而达到开发各种通信信号功率谱分析的实验以及各种数字接收机误码率测试的实验目的,同时这种计算机仿真的实验方式不仅提高了学生的学习兴趣,而且可以做到了缩短技术开发及制作的周期并降低了研发成本的目的。In order to solve the problem of partial experiments undone in ＂the principles communication＂ course due to hardware experimental system＂ s limitations, this paper adopts MATLAB software simulation method .Through two examples of MPSK system bit error rate test and all kinds of digital communication signal power spectral density analysis experiment, the randomicity of the hardware signal source is sloved and the lack of filter defects in experimental systems is made up, so as to achieve the development of a variety of communication signal power spectrum analysis of experimental as well as digital receiver BER test purposes. While at the same time the computer simulation experiments not only increase the students＇ interest in learning, and can shorten the technology development and production cycle and reduce development cost.
