A special of construction of multi-wavelet
Yan-Xin Xu, Zuo-Xian Fu, Siqi Li · 2013
In this paper, a tight single-orthogonal wavelet support on the basis of its translation as a number of wavelet functions to construct the two-tight support symmetric multi-wavelet is given. The method which constructs multi-wavelet smooth approximation is simple and easy. The support length is shorter than the single wavelet. The proposed method in this paper has a better practical value.
