摘　　要：通信原理是一门理论性强、公式多、难理解的课程,通过仿真来加深知识点的理解,使抽象的内容更加直观化。根据不同的通信系统性能,考虑两个重要性能指标——有效性和可靠性,通过Simulink仿真,分析不同的编码解码方式。以DM和ADM编解码系统为例,详细介绍一种仿真实验的方法,通过重点阐述通信系统的构建,及其不同输入信号的比较,仿真得出不同实验结果,从而推出在不同的应用场合运用不同的编码解码方式。从而培养了学生通信思维和通信意识,提高了其通信能力和设计的能力。Communication principle is a course with strong theory, many formulas and difficult to understand. Through simulation, it can deepen the understanding of knowledge points and make the abstract content more intuitive. According to the performance of different communication systems, two important performance indicators-effectiveness and reliability are considered, and different encoding and decoding methods are analyzed through Simulink simulation. Taking the DM and ADM codec system as an example, a simulation experiment method is introduced in detail. By focusing on the construction of the communication system and the comparison of different input signals, different experimental results are obtained through simulation, so that different encoding and decoding methods can be used in different applications. In this way, students’ communication thinking and awareness can be cultivated, and their communication ability and design ability improved.
