【Abstract】 Priority should be put on improving the signal-to-noise ratio in the digital processing of the seismic signals. The writers studied the application of some commonly used wavelet noise elimination methods to remove the random noise,and respectively analyzed their characteristics and improved the calculating methods. The simulation results of MATLAB show that the noise elimination processing of seismic signals based on wavelet transform is apparently better than the traditional Fourier method.更多还原
