摘要
AM、DSB调制是通信系统中最重要的、最基础的调制之一。本文首先分析了AM、DSB调制的原理,然后运用MATLAB仿真平台设计了这两种调制的仿真模型。通过仿真,观察了AM、DSB信号调制过程中各环节的时域和频域波形。最后,在仿真基础上分析比较了这两种调制方式的性能。
AM modulation and DSB modulation is one of the most important and fundamental modulation in communication system.This paper first analyzed the principle of AM modulation and DSB modulation,then used MATLAB simulation platform to design the two kinds of modulation simulation model.The time domain and frequency domain waveforms of AM and DSB signal modulation were observed by simulation.Finally,the performances of the two modulation modes were compared on the basis of simulation.
