Univariate 3-channel Wavelet Filter Banks from Centrally

Junqiao You, Qiuhui Chen, Yi Wang

Abstract


In this note, we design a family of univariate three channel wavelet filter banks by using centrally symmetric matrices. We offer an explicit structure for centrally symmetric and orthogonal matrix of order 3 and then use it to generate filter banks. For low pass filter of this type, the matrix extension to construct high pass filters is easy to realize.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not.
