摘要
对小波变换抑制干扰信号提取真实信号的3种方法,即小波滤波器消噪法;软、硬阈值消噪法;基于模极大值的小波去噪方法,进行了比较研究.给出了每种方法的适用范围及具体的算法、仿真结果,对于选用小波变换工具进行信号处理具有一定的理论意义和实用价值.
Three methods to restrain interfering signals and to extract real signals were studied based on wavelet transform. They are the method of wavelet transform filter, the method of soft or hard threshold noise reduction, and the method of modulus maximum value. Comparing the three methods, the concrete arithmetic and simulating results are presented. For selecting compatible wavelet transform tools to process signals,these methods have definite theoretical significance and use value.
