Oversampling of wavelet frames for real dilations
wavelets affine frames real dilations Second Oversampling Theorem shift invariant subspaces
2012/4/16
We generalize the Second Oversampling Theorem for wavelet frames and dual wavelet frames from the setting of integer dilations to real dilations. We also study the relationship between dilation matrix...
Stability of the Recovery of Missing Samples in Derivative Oversampling
frame Riesz basis shift-invariant space sampling formulas
2010/12/3
This paper deals with the problem of reconstructing a band-limited signal when a nite subset of its samples and of its derivative are missing. The technique used, due to P.J.S.G. Ferreira, is based o...
