随着通信原理成为通信类专业中最重要的一门基础课程，它的教学和研究也变得尤为重要，计算机仿真则成为重要手段之一。本文根据通信原理课程的发展及教学需求，重点介绍了利用MATLAB软件设计通信原理仿真平台的基本原理及功能，并利用MATLAB软件提供的图形用户界面，给出了基于MATLAB的通信原理仿真平台的GUI设计。该平台针对通信原理教学及实验要求，利用设计向导GUI提供的设计工具，开发出了多个仿真界面，仿真出通信原理的多个教学实验内容。该平台界面设计简单，结构一体化，具有很强的演示性，且可视性强，操作简单方便，以图形及动态仿真演示了通信原理中部分抽象的内容及波形，能为教师和学生提供简单但高效率的教学辅助。 关键字：通信原理； MATLAB； 仿真平台； GUI设计
ABSTRACT
With communication principle becomes the most important of basic courses in communication kind of professional, Teaching and Researching has became more and more important, and the computer simulation has became one of the important means. According to the communication principles of curriculum development and teaching needs, the article focusing the basic principles and functions of the communication theory simulation platform using MATLAB software design, and using the MATLAB software provides a graphical user interface that gives a GUI based on MATLAB simulation platform of communication theory design. The platform aim at experiments and teaching requirements of communication principle, use design wizard GUI provide design tool, developed a number of multiple simulation interface, and simulated more examples in communication teaching experiment content. This platform interface is simple in design, structure integration, with a strong demonstration, and the visibility is strong, easy to operate, graphics and dynamic
