这是小波变换用来去噪的程序，对信号的去噪效果较好-wavelet denoise

提升小波变换的MATLAB程序，适合于故障诊断中的信号分析和处理-Lifting Wavelet Transform MATLAB, signal analysis and processing for fault diagnosis

连续小波变换程序，主要功能是对调制信号进行连续小波变换，一定程度上能起到解调的作用-Continuous wavelet transform procedure, the main function is continuous wavelet transform of the modulated signal, to a certain extent, can play the role of demodulation

语音信号小波去噪 在小波基 db3 下进行一维离散小波反变换 对输出信号抽样点值进行归一化处理-Speech signal wavelet de-noising in wavelet bases ' db3' one-dimensional discrete wavelet transform on the output signal sample point value normalization
