Strong Ability

The Frequency-Shift Keying (FSK) signal is frequently used in track circuits because of the strong ability of resistance interference. Symbol rate is one of the important signal parameters for safety of railway. The paper propose a algorithm of high precise detectation of FSK signal using Chirp-Z transform; Theoretically gives the detailed explanation to the major technique, and has carried on the Matlab simulation, The simulation result indicates this method during the enhancement is shifted signal examination precision, reduced the computation order of complexity.
