| Abstract: | According to the theory of the second generation wavelet transform, the improved algorithm is proposed and the optimum-interval interpolation estimation is used to design the predictor. To verify the effectivity of the improved algorithm, it is applied in the noise reduction. Results of the noise reduction by using the improved algorithm are compared with results of second generation wavelet transform and the traditional wavelet transform. The improved algorithm is proved to be effective in the noise reduction. |
