摘　　要：分析当前通信原理课程实验教学存在的问题,提出采用Matlab仿真弥补实验室实验设备等的不足。给出利用Matlab函数实现多进制数字调制(包括4ASK,4FSK和4PSK)的仿真实例,将抽象的原理形象化。给出部分仿真程序,并对仿真结果进行分析和讨论,仿真结果与理论结果一致。这里将Matlab仿真用于多进制数字通信,解决了当前实验设备不能做此类实验的尴尬境地,为相关领域的研究指出了一个实验方法,是实验教学改革进程中的有益尝试。The problems of communication principle course experimental teaching are analyzed, and Matlab simulation is adopted to make up the laboratory is put forward. Some simulation examples about multi - decimal digitial modulation are given,including 4ASK,4FSK and 4PSK. Moreover,it enables the abstract principle visualization. Some simulation procedure are described and the simulation results are analyzed. It is indicated that the simulation results are identical to theoretical resuits. Matlab is applied to multi - decimal digitial communication and resolution of some experiments can＇t be made with current experimental equipments. An experiment approach is proposed for some related areas. It is also a beneficial trial in experimental teaching reform.
