基于FSK可变载频调幅广播的应急广播覆盖仿真研究

Simulation of Emergency Broadcasting Based on FSK-AM

本文提出了一种用于应急广播中短波调幅覆盖的新方案,将数字信号进行FSK调制,然后用此FSK调制信号取代调幅载波信号,以达到传输窄带数字应急消息的目的。本文利用MATLAB对这种基于FSK可变载频调幅广播的应急广播覆盖就行了仿真分析,并给出了仿真结果。

This paper presents a new scheme for AM broadcasting. The digital signal is modulated by FSK, and then the FSK modulation signal is used to replace the AM cartier signal, so as to achieve the purpose of transmitting the narrowband digital emergency message. In this paper, MATLAB is used to simulate the emergency broadcasting of AM broadcasting based on FSK variable carrier, and the simulation results are given.
