摘要
本文针对音频无绝缘轨道电路 ASK信号的特点,提出了一种新的音频无绝缘轨道电路 ASK信号解调算法-ZFFT频谱解调算法,并基于TMS320C32设计了接收信号解调系统。实验结果表明该系统能可靠地解调ASK信号,满足现场要求.
As paper aiming at the characteristic of the ASK signal in uninsulated Audio Frequency Track Cir- cuit presents a new algorithm to demodulate the ASK signal -the demodulation algorithm of ZFFT,designs a demodulation system on the basis of TMS320C32 The result of experimentation shows that the system can demodulate the ASK signal reliably It accords with the requirement in locale
