A Signal De-noising Algorithm base on Improved Wavelet Coefficients Reconstruction
Kui Cao · Journal of Xinyang Normal University · 2008
An improved signal denoising algorithm, which uses a cubic spline interpolation algorithm to reconstruct wavelet coefficients after denoising based on Modulus Maximum Principle, is presented in this paper, and then the signal is recomposed using the mallat algorithm based on the reconstructed coefficients. Experiments show that the approximate wavelet coefficients of the original signal are offered by using this algorithm, and denoising effect is obvious.
