【Abstract】 Orthogonal multi wavelets can have short support,symmetry or anti symmetry and orthogonality simultaneously,which there no exist a general single orthogonal wavelet,so that poses more superiority in signal processing and gains a better results.The paper elaborated on the principle of noise suppression processing by using GHM orthogonal multi wavelets for seismic signal and gave real examples to show the effectiveness of the method.更多还原
