摘　　要：设计功能齐全、实现灵活、移植方便的数字通信实验软件平台对于现有硬件数字通信实验平台进行验证和补充扩展,将有助于教学工作的展开。基于Matlab GUI功能的数字通信实验软件平台的设计与实现主要包括完整通信过程的仿真实现及其界面设计,其中,"完整通信过程实现"重点围绕采样、编码、调制、扩频等技术展开,并引入了信道中的噪声和衰落,能够更好地模拟实际通信系统的通信状况。教学实践证明:软件实验平台能够加深学生对于数字通信理论知识的掌握,并通过和实际硬件通信系统平台相结合,进一步锻炼学生的实践动手和自主综合设计能力。学生通过独立设计、调试程序,并与实际电路比对、测量,增强了学习的兴趣和积极性。Design of a full-featured, flexible and portable digital communication experiment software platform can validate and complement the expansion for the existing hardware ＂ Digital Communication Experiment Platform＂, which can contribute to and supplement the teaching activities and effects. The design and implementation based on Matlab GUI functions for ＂ Digital Communications Experiments Software Platform＂ include the simulation of the complete communication process to achieve its interface design. The complete communication process focuses on sampling, coding, modulation, and spread spectrum technologies, and also the channel noise and fading to match the actual communication environments. Teaching practice shows that this software experimental platform can enhance students ＇ mastery of the digital communication theory, and harden their experimental and self-design capabilities through the combination of actual hardware measures and software design process. Moreover, the students＇ interests in learning and motivation can he improved by independent design, debugger the program, and in contrast with measures of the hardware platform.
