| Abstract: | A new algorithm based on nonlinear filters and lifting schemes is suggested in the signal denoising. The class of nonlinear filters is designed as predictor due to the design flexible of lifting scheme. Numerical experiments show that this method is efficient and better than that with nonlinear filters only. |
