2006 Perturbation of Regular Sampling in Shift-Invariant Spaces for Frames
abstract
Perturbation theorems for regular sampling in shift-invariant spaces are derived using a generalized perturbation theorem for frames in a Hilbert space, which generalizes the irregular sampling theorem established by Chen Using this generalized irregular sampling theorem, estimates for the maximum perturbation are obtained. Some typical examples illustrate the result

2004 Frames and sampling theorems for translation-invariant subspaces
abstract
A sampling theorem for frames in translation-invariant subspaces of L/sup 2/(R) is established, which is a generalization of a result of W. Chen and S. Itoh for Riesz bases (see IEEE Trans. Sig. Processing, vol.46, p.2822-4, 1998). Then, some necessary conditions for sampling are derived for Riesz bases. Some relationships and properties are also derived about the relevant functions.
