In this paper, the traditional wavelet hard threshold algorithm is studied, the advantages and disadvantages of the traditional hard threshold algorithm are analyzed, and then based on the research, a new algorithm is proposed to overcome the shortcomings of traditional algorithms. The new algorithm is compared with the traditional one. After rigorous theoretical proof and experimental verification, the results show that the new algorithm has good operability and is easy to implement. It shows strong denoising ability when dealing with high-frequency signals. Therefore, To a certain extent, make up for the shortcomings of the traditional algorithms, has a good prospect.
