针对通信系统的基本构成,应用Matlab/Simulink软件对模拟通信系统和数字通信系统建模并分别对其进行振幅调制和解调的仿真.对模型进行分析并发现,通过Matlab/Simulink的各功能模块可以建立清晰的模拟通信系统和数字通信系统,且仿真结果有效验证了模拟和数字通信系统中关于振幅调制和解调的基本功能.故若将该仿真模型及仿真过程引入课堂教学,可以加深学生对通信理论课程中关于振幅调制和解调的基本系统构成及原理的理解.

In accordance with the basic composition of communication system,the Matlab/Simulink software was applied to model the analog communication system and the digital communication system,and carry out simulations of amplitude modula?tion and demodulation separately. The model was analyzed. It is found that the clear amalog and digital communication systems can be established with all the function modules of Matlab/Simulink. Morever the simulation results verified the basic functions of amplitude modulation and demodulation of the amalog and digital communication systems. Especially if the simulation model and process is introduced into classroom teaching,it can deepen students′ understanding on the basic principle and basic sys?tem composition for the amplitude modulation and demodulation in the communication course.
