地震信号处理当中应用小波去除面波干扰，小波变换后进行阈值处理，反变换之后得到面波压制后的地震信号-Surface wave seismic signals obtained after the seismic signal processing to suppress them after removing the surface wave interference wavelet, wavelet transform thresholding, anti transformed

esprit algorithm signal frequency interference can be assessed Constituting the modulated signals of different frequencies, Based on wavelet transform digital watermarking algorithm matlab code.
