小波分析有它独特的特点。它的压缩比高、压缩速度快 , 压缩后能保持信号与图像的特征基本不变 ,且在传递过程中可以抗干扰。可以克服传统方法产生的缺陷 ,因此获得了较好的压缩效果。 -Wavelet analysis has its unique characteristics. Its high compression ratio, compression speed, compressed to maintain the basic characteristics of the sign

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.
