摘要
铁路FSK是一种低频调制中心载频的移频信号.为实现对ZPW-2000系列发码设备所发出FSK信号的准确解调,设计了一种新的基于浮点DSP的铁路FSK信号检测系统.通过实际测试,该系统能够快速准确检测出FSK信号解调后的各种信息.
Railway FSK signal is a kind of low-frequency modulated carrier frequency signals. In order to achieve accurate demodulation of the FSK signals sent by ZPW-2000 series code-transmitting device, a new railway FSK signal detection system based on Floating-point DSP technology is designed. Tests have been macle to the system and the results show that it can detect various data rapidly and accurately after the dcmodulation of FSK signals.
