| Abstract: | Multiwavelet possesses such very important properties in signal processing as orthogonality,symmetry,and short support,which makes up for the shortcoming of scalar wavelet,and takes on broader application prospects.This paper,from the aspect of filtering,mainly analyzes and designs multiwavelet filter.The processing method for multiwavelet coefficients is also presented in the paper.The simulation indicates the advantages of multiwavelet. |
