摘要
利用小波方法去噪是小波分析工程实际的一个重要方面。简单介绍了小波分解和重构,小波去噪原理,硬阈值法、软阈值法、平移不变量法。并且利用Matlab将几种典型的信号叠加高斯白噪声进行仿真。
TUsing wavelet denoising is an important application of wavelet analysis in engineering.Some methods are introducing including wavelet decompotion and reconstruction, wavelet denoising theory, hard thresholding, soft thresholding and translation invariant methods.Some methods are used to remove the Gaussian white noise from some typical simulated signals by using Matlab.
