Simulink软件在通信原理课程教学中的应用

Research on Application of Simulink in Communication Principle Teaching

针对Simulink软件和通信原理课程的特点及教学中存在的问题,文章提出在理论教学中引入该软件辅助教学,以该课程的通信原理重难点AM、2DPSK和PCM/DPCM系统为例,详细阐述了仿真电路搭建、参数设计以及波形分析等过程.实践结果表明:该软件应用到通信原理课程教学中可完整并准确地完成数字调制与解调,且波形能可视化显示,学生学习积极性大幅提升,理解力和分析力得到提高,教学质量得到进一步改善.

In view of the characteristics of simulink and communication principle courses and the existing problems in the teaching,this paper proposes to introduce the software to assist the teaching in the theoretical teaching,taking AM,2DPSK and PCM systems as examples to describe the simulation circuit construction,parameter design and waveform analysis and other processes in detail.The practical results show that the software can complete digital modulation and demodulation completely and accurately when applied to the teaching of communication principle course,and the waveform can be visualized to show that students’learning enthusiasm is greatly enhanced,at the same time their comprehension and analysis ability are improved,and the teaching effect is good and the teaching quality is further improved.
