基于System View的FM语音通信系统设计

Design of FM Voice Communication System Based on SystemView

采用ELANIX公司的SystemView软件,建立了一个双路FM语音通信系统仿真模型。以波形文件作为信号源,频率调制直接使用SystemView函数库FM,解调则使用延时相乘结构来实现,信道用高斯白噪声来模拟。仿真结果表明,接收端能正确地解调出相应信号,实现了FM语音通信系统的基本功能。

A simulation model of dual-line FM voice communication was made using SystemView software of Elanix company. It used wave file as signal source, achieved frequency modulation by FM module in SystemView function library, demodulated with delay-multiply structure, and simulated in the AWGN channel. The result showed that the corresponding signal could be demodulated by the receive end and the basic functions of FM voice communication system were achieved.
