Method and prospect of earthquake signal

The processing method of earthquake signal has been a difficult point in the research of signal and it is also a difficult and hot spot to detect earthquake wave. In recent years, earthquake signal processing methods have been improved, but still need to be improved. Summarize and analysis comparison to the traditional methods in the amplitude domain analysis, Fourier transform, short-time Fourier transform and the modern method about the Gabor transform, wavelet transform, Wigner-Ville Random transform, high resolution Random transform's development characteristic and application. Finally, make a conclusion and prospect the future.
