说明：  介绍了小波二进制变换的基本原理 , 简述了小波变换奇异性和信号突变的关系。 基于小波变换, 给出一种结合3R 准则、 软硬阈值折衷法的奇 异信号小波检测方 法。仿真结果表明此法 既能有效地消除噪 声, 又能较好 保留奇异信号
(This paper introduces the basic principle of binary wavelet transform, signal singularity and wavelet transform are briefly discussed the relationship between the mutation. Based on wavelet transform, a combination of 3 r principles, hard and soft threshold eclectic method of different signal wavelet detection method. The simulation results show that this method can effectively eliminate the noise, and can keep the singular signal )
