This paper inroduce a kind of closes detection demodulation algorithm mutually to be used in train traffic signal. Make the various signals of high frequency send to DSP to be handled, and draw the low frequency signal of train control, in order to analyze carrier frequency information and the low frequency information. Give the analysis explanation to the cross-correlation detection algorithm flow. Proposes realization plan this algorithm on the DSP. And give the part empirical datum. The cross correlation demodulation algorithm has high-speed calculation, high precision,anti-jamming and low hardware requests. After several test, the ATP system is absolutely accordant to the standard.
