FSK (Frequency Shift keying) signal
which has advantages of narrow-bandwidth
strong anti-interference ability
long transmission distance and so on
is used in jointless Frequency-shift track circuit to send different kinds of control signals. However
as FSK is non-linearly modulated
parameter estimation with high accuracy is hard to realize. Based on the spectrum analysis complement with time-frequency distribution
a highaccuracy FSK signal parameter estimation algorithm is put forward in this paper. According to the signal characteristics
under-sampling and ZFFT are used to improve the accuracy of spectrum analysis
and the base frequency resolution meets system requirement of 0.02Hz. Wigner-Ville distribution has an excellent time-frequency concentration while serious cross-term interference at the same time. Through the design of kernel function
the cross-terms are almost suppressed and the upper/down side frequency resolution meets the system requirement of 0.2Hz. The effectivities of all the methods mentioned above have been proved by MATLAB simulation
which pave a solid way for the development of high-accuracy FSK signal parameter estimation devices. 2008 IEEE.
