摘要
Abstract
A new adaptive filter based on wavelet transform is designed. First, the original signal is decomposed by wavelet transform and the wavelet coefficients with main noises are canceled. Second, the reconstruction signal is selected as the original input of the adaptive filter and the wavelet coefficients with main noises are selected as the reference input of the adaptive filter. The experimental results show that this method is of bigger SNR and satisfied de-noising result. Finally, less computation of the method is very suitable for computing DCG signal with large amounts of data.关键词
