摘　　要：针对学生在学习“信息论与编码”课程中感觉理论性强、抽象难理解的问题,该文在MATLAB的环境下基于GUI设计了一套数字图像传输系统。该系统涵盖了通信系统模型的各个步骤,包括信源(图像输入)、信源编码、信道编码、模拟信道、信道译码、信源译码、信宿(图像输出)等。通过该平台模拟整个通信过程,得到了带有传输误差的图像输出。通过对通信系统模型中任一模块以不同方案得到的不同图像结果进行分析,可直观对比该模块中各种方案的优劣。该平台界面操作简单,参数调节灵活,可脱离MATLAB环境独立运行,方便教学演示。Aiming at solving the problem that students feel that the content is theoretical, abstract and incomprehensible in the “Information theory and coding” course, this paper designs a set of digital image transmission system based on GUI under the MATLAB environment. The system covers the various steps of the communication system model, including seven parts such as source(image input), source coding, channel coding, analog channel, channel decoding, source decoding, and sink(image output). The entire communication process is simulated through this platform, and image output with transmission errors is obtained. Through the analysis of different image results obtained by any module in the communication system model, the advantages and disadvantages in the module can be intuitively compared. The interface of the platform is easy to operate, and the parameters can be adjusted flexibly. It can run independently without MATLAB environment and is convenient for teaching demonstration.
