Wavelet Filter Functions, the Matrix Completion Problem, and Projective Modules over C(t N )
We discuss how one can use certain filters from signal processing to describe isomorphisms between certain projective C(T)-modules. Conversely, we show how cancellation properties for finitely generated projective modules over C(T) can often be used to prove the existence of continuous high pass filters, of the kind needed for multi-wavelets, corresponding to a given continuous low-pass filter....
متن کاملDesign and Comparative Study of Digital FIR Filters using Improved Particle Swarm Optimization
In order to reduce the effect of Inter Symbol Interference (ISI) in a digital communication system, different types of transmitting pulse shaping filters have been extensively used in practice. We need to design these filters with some constraints imposed by requirements of the communication system in which we are going to use them. The use of optimization techniques have been proved to be quit...

Wavelet decomposition of signals using the classical Daubechies-Wavelets could also be considered as a decomposition using a filter bank with two channels, a low pass and a high pass channel, represented by the father and mother wavelet, respectively. By generalizing this two channel approach filter banks with N ≥ 2 channels can be constructed. They possess one scaling function or father wavele...
متن کاملSynthesis of Wavelet Filters using Wavelet Neural Networks
An application of Beta wavelet networks to synthesize pass-high and pass-low wavelet filters is investigated in this work. A Beta wavelet network is constructed using a parametric function called Beta function in order to resolve some nonlinear approximation problem. We combine the filter design theory with wavelet network approximation to synthesize perfect filter reconstruction. The order fil...
متن کاملDesign of Dyadic-integer-coefficients Based Bi-orthogonal Wavelet Filters for Image Super-resolution Using Sub-pixel Image Registration
This paper presents image super-resolution scheme based on subpixel image registration by the design of a specific class of dyadicinteger-coefficient based wavelet filters derived from the construction of a half-band polynomial. First, the integer-coefficient based halfband polynomial is designed by the splitting approach. Next, this designed half-band polynomial is factorized and assigned spec...
