Discrete-Time Wavelets: Time-Frequency Localization, Shift-Invariance, Modeling Of Linear Time-Invariant Systems
14 It is shown further how the discrete wavelet transform can be shift invariant in the sense that the coecients of the transform at a scale for a shifted sequence can be computed from the coecients at the same scale from the original sequence. We derived conditions for the analyzing lters in order to obtain that kind of shift invariance. The transfer functions of the lters must not overlap wit...
متن کاملThe spectral function of shift-invariant spaces on general lattices
We extend the notion of the spectral function of shift-invariant spaces introduced by the authors in [BRz] to the case of general lattices. The main feature is that the spectral function is not dependent on the choice of the underlying lattice with respect to which a space is shift-invariant. We also show that in general the spectral function is not additive on the orthogonal infinite sums of S...
متن کاملSubspace Lattices of Finite Vector Spaces Are 5-generated
Let n ≥ 3. From the description of subdirectly irreducible complemented Arguesian lattices with four generators given by Herrmann, Ringel and Wille it follows that the subspace lattice of an n-dimensional vector space over a finite field is generated by four elements if and only if the field is a prime field. By exhibiting a 5-element generating set we prove that the subspace lattice of an n-di...
متن کاملTime-Frequency Localization and the Gabor Transform
The time-frequency content of a signal can be measured by the Gabor transform or windowed Fourier transform. This is a function defined on phase space that is computed by taking the Fourier transform of the product of the signal against a translate of a fixed window. The problem of finding signals with Gabor transform that are maximally concentrated within a given region of phase space is discu...
متن کاملThe structure of finitely generated shift - invariant spaces in L
A simple characterization is given of finitely generated subspaces of L2(IR) which are invariant under translation by any (multi)integer, and used to give conditions under which such a space has a particularly nice generating set, namely a basis, and, more than that, a basis with desirable properties, such as stability, orthogonality, or linear independence. The last property makes sense only f...
