摘要
利用System View实现了AM通信系统。在发送端,产生了临界调幅的AM信号,信道考虑了加性高斯白噪声信道,接收端采用相干解调器解调。利用Sink库显示模块显示了AM系统中的标志性波形,并利用System View的分析功能求出各标志性信号的频谱并予以显示。实验表明,System View非常适合通信原理课程实验。
AM communication system is implemented by using System View software. The critical amplitude modulation is generated in the transmitter,additive Gaussian white noise is considered in the channel,coherent demodulator is used to demodulate in the receiving end. Typical waveforms in a AM communication system are displayed by the display module in the Sink library,spectrums of typical signals are calculated and displayed by using spectrum analysis function of System View. Experiments show that System View is very suitable for communication principle course experiment.
