摘要
针对扩频通信的教学实验问题,将Simulink工具引入实际教学,介绍了Simulink的通信模块,并搭建了扩频通信的发信,传输以及收信的基本链路,仿真结果可即时显示出扩频通信传输过程中误符号率,错误符号数以及总符号数的变化情况,有效提高了教学效果。
In order to solve the teaching experiment problems in spread spectrum communication,Simulink tools are taken into actual teaching.The communication blockset is introduced in this paper,and the basic links in spread spectrum communication are established,which respectively are source,transmission and sink.Simulation results shows that this system can inmediately show the symbol error rate,the number of error symbols and the total number of symbols,which enables to improve the teaching quality.
