Research of Modulation and Demodulation of Inbound Signal of Two-way Automatic Communicatio

  • 摘要: 文章介绍了双向工频通信系统的基本原理及入站信号的调制和解调方法,详细地介绍了采用FIR滤波器及数字差分方法对入站信号进行提取的方法,并用Matlab/Simulink建立了基于配电网的仿真模型。对入站信号调制与提取的仿真研究验证了文中所述方法的正确性。

     

    Abstract: The paper introduced the basic principle of two-way automatic communication system and method of modulation and demodulation of inbound signal, described method of using FIR filter and data difference method to demodulate inbound signal, and used Matlab/Simulink to establish a simulation model based on distributed network. The simulation research for modulation and demodulation of inbound signal proved the method is correct.
