基于小波阈值去噪的技术研究

Using wavelet de-noising is an important application of wavelet analysis in engineering. The wavelet threshold de-noising is one of the major methods of de-noising in the wavelet domain. This paper firstly describes the basic theory, the basic procedures and three algorithms about the wavelet threshold de-noising. And then according to the de-noising simulation by Matlab software, this paper gives the influencing factors about the wavelet threshold de-noising and the advantages and disadvantages of each method.
