New Orthogonal Multiwavelet Filters Derived by Matrix Spectral Factorization
Vasil Kolev, Todor Cooklev, Fritz Keinert
The paper considers the construction of two new orthogonal multiwavelets with supercompact support by using the Fast Bauer's method for matrix spectral factorization on the matrix…
Bauer's Spectral Factorization Method for Low Order Multiwavelet Filter Design
Vasil Kolev, Todor Cooklev, Fritz Keinert
Para-Hermitian polynomial matrices obtained by matrix spectral factorization lead to functions useful in control theory systems, basis functions in numerical methods or multiscalin…
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…
A Kaczmarz Algorithm for Solving Tree Based Distributed Systems of Equations
Chinmay Hegde, Fritz Keinert, Eric S. Weber
The Kaczmarz algorithm is an iterative method for solving systems of linear equations. We introduce a modified Kaczmarz algorithm for solving systems of linear equations in a distr…
