虚拟仿真技术在通信原理课程教学中的应用实践
|
摘要
为了提高学生对通信原理课程的学习兴趣和工程实践能力,本文以通信原理课程的二进制相移键控2PSK数字通信为例,利用MATLAB/SIMULINK的通信模块搭建2PSK数字通信系统模型,虚拟仿真实现频带传输中的调制和解调过程。SIMULINK建模的快捷、灵活和便于观察的优点,极大地激发了学生的学习通信原理课程的主动性和探索精神,使通信原理教学取得了良好的效果,为后续移动通信、无线通信和通信网技术的学习打下了基础。
In order to enhance students' study interests and the practical ability in Communication Principle course teaching,this paper takes Binary Phrase-Shifting Key( 2 PSK) as an example,creates 2 PSK digital communication system model by MATLAB/SIMULINK. and virtually simulates to achieve modulation and demodulation in frequency band transmission. The advantages of SIMULINK's fast,flexible and easy-to-observe have greatly stimulated the students' initiative and exploration spirit in learning Communication Principle Course,and made the communication principle teaching achieve good results,which will lay a foundation for the subsequent study to Mobile Communication,Wireless Communication and Communication Networks Technique.
