摘要
介绍了小波变换及其Ｍａｌｌａｔ算法，阐述了小波变换压噪原理，并用其方法对合成地震信号与实际地震记录进行了处理。
In this paper, wavelet transform(WT) and its Mallat algorithm have been stated briefly. And the principle of rejecting noise with WT has been presented in detail. And processing of synthetic and real seismic data by means of the method has been made.
