摘要

吴爱弟 ,曹思远 .用正交多小波压制地震信号的随机噪声 .石油地球物理勘探 ,2 0 0 2 ,37(5 ) :4 73～ 4 76　　正交多小波可同时具有短支集、对称性或反对称性和正交性 ,这是一般的正交单小波所没有的性质 ,因而在处理信号时能取得更好的效果。本文详细说明了应用 GH M正交多小波对地震信号进行去噪处理的原理 ,并给出实际例子说明该方法的有效性。
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.
