基于Matlab的幅度调制信号仿真研究

Simulation Study of Amplitude Modulation Signal Based on MATLAB

通信系统的仿真是研究通信系统性能的有效手段,很多通信理论比较抽象不易理解,而利用Matlab进行仿真把抽象的东西形象化,便于深刻理解。本文在介绍幅度调制原理的基础上,利用Matlab/Simulink工具箱,对模拟幅度调制系统——常规双边带调幅(AM)、抑制载波双边带调幅(DSB-SC)、单边带调幅(SSB)进行了仿真实现。

Communication system simulation is the eltective means to study the performance of communicalion systems. Communication theory is often too abstract to understand, but simulation using Matlab makes the abstract theory visualize, and facilitate deep understanding. This paper introduced the principle of amplitude modulation and using Matlab / Sinmlink toolbox simulated the amplitude modulation system - conventional bilateral with AM （ AM）, Amplitude modulation with carrier suppression bilateral （ DSB - SC）, single sideband amplitude modulation （SSB）.
