论文题目：专 业：通信工程 ： 签名： 指导教师： 签名： 摘 要 通信原理是通信工程、电子信息类专业的重要专业基础课程，也是许多学校通信、信息专业研究生入学考试的必考科目。在传统的教学和设计中，主要采用的方法是手工分析与电路板试验，而该课程大部分是较为繁琐的理论和推导，因此容易使学生感到乏味和难以接受。利用MatlabGUI为平台设计开发的通信原理演示系统，克服了传统方法的局限性。该系统具有可视化、交互性良好、操作便捷等优点，是未来教学和设计运用的趋势。 本文在介绍模拟线性调制解调、模拟信号数字化、二进制数字调制解调、和信道编码理论的基础上，利用Matlab语言进行GUI编程实现交互式实时动态演示系统的设计，并对该平台进行测试及结果分析。设计出的演示系统参数可变，测试结果正确，各模块间逻辑结构清晰，整体运行稳定，更有利于教师的授课讲解和学生的学习理解。 通信原理 演示系统 Matlab 图形用户界面（GUI）Title：emonstration System About Communication Theory Based on Matlab GUI Major：ommunication Engineering Name： Signature： Supervisor：Zhang Ming Signature： ABSTRACT Communication Theory is a communication engineering, electronic information professional foundation courses, many schools in communication and information professionals compulsory subjects of the Graduate Record Examination. In the traditional method of teaching and design, manual analysis and circuit board test are currently used, and more than that, a lot of theoretical knowledge and complicated reasoning often make the students feel confused. In order to solve these problems, we introduce a GUI system which is based on Matlab platform. It can provide more demo content and help students understand the theory more easily and intuitive. In addition, it is simple to operate, interact well and can return accurate result quickly. We all think it is the trend of development and will be widely used. This paper we introduce some theoretical knowledge first, which include analog linear modulation and demodulation，Digitization of analog signals, Binary digital modulation and demodulation and channel coding theory ,and then we implement a simulation system based on Matlab GUI. We can provide the test parameters and system will return the result correctly. What is more the logical structure of each module is clear and the system running stable. All of that are conductive to either the teachi
