In order to acquire the information of railway binary frequency-shift keying signals  which include upper/down side frequencies and base low-frequency with high-accuracy  a novel frequency detection algorithm for France UM-71 system is proposed. Combining fast Fourier transform with the ratio correction method  the carrier frequency and the base frequency are obtained. Furthermore  the hardware consumption has been decreased. And it possesses the advantage of simple algorithm and fast operation speed. Comparing with the detection of the base frequency  the upper/down side frequency of railway signal is more difficult. Based on spectrum analysis and the spectrum correction  a new method  which adopts the sliding window  is put forward in this paper. The absolute differences between the upper side frequencies and the down side frequencies obtained are regarded as the criterion for judgment. Then the set of data  in which the maximum absolute value is  is to be the result of the upper/down side frequency. Because the sliding window will go through every stage when the upper/down side frequency changes  therefore  it is not sensitive enough to the position of data which need to be transformed. Using the method mentioned above  the experiment results show that the accuracy requirement of the side frequency is satisfied well. 2008 IEEE.
