摘　　要：扩频通信通过扩展信号频带宽度以提高抗干扰能力和保密性,但其概念抽象,内容复杂,为课程的学习带来一定的难度。基于此,利用MATLAB软件中GUI设计一种适用于直接序列扩频系统的仿真实验演示平台,该平台可根据参数设置,给出系统中不同功能模块输出的仿真和测试结果。教学实践结果表明,该平台能够直观地显示系统中信号在时域和频域上的变化,使得学生对直接序列扩频通信系统有着更深入的理解。Spread spectrum communication technique has strong ability of anti-interference and high security by spreading signal spectrum, while its concepts are abstract and complicated. Based on this, a demonstrating and experimental platform of direct sequence spread spectrum communication system is designed by MATLAB GUI. This platform provides the corresponding simulation results of signals in the system according to different input parameters. Teaching practice shows that this platform can directly display the change of signals in the time domain and frequency domain, which can deepen the students’ understanding of direct sequence spread spectrum communication system.
