Design of a Simple Orthogonal Multiwavelet Filter by Matrix Spectral Factorization
Vasil Kolev, Todor Cooklev, Fritz Keinert
We consider the design of an orthogonal symmetric/antisymmetric multiwavelet from its matrix product filter by matrix spectral factorization (MSF). As a test problem, we construct…

Matrix Spectral Factorization for SA4 Multiwavelet
Vasil Kolev, Todor Cooklev, Fritz Keinert
In this paper, we investigate Bauer's method for the matrix spectral factorization of an r-channel matrix product filter which is a halfband autocorrelation matrix. We regularize t…
