Restoring lost samples from an oversampled signal in shift invariant spaces
نویسندگان
چکیده
It is well known that any finite missing samples of a band-limited signal can be recovered from the remaining known samples when the signal is oversampled at a rate higher than the minimum Nyquist rate. We consider a similar problem for an oversampled signal in shift invariant spaces with compactly supported continuous Riesz generators. Using a multi-channel oversampling, we find conditions under which finitely many missing samples can be recovered.

Shift Invariant Spaces and Shift Preserving Operators on Locally Compact Abelian Groups
We investigate shift invariant subspaces of $L^2(G)$, where $G$ is a locally compact abelian group. We show that every shift invariant space can be decomposed as an orthogonal sum of spaces each of which is generated by a single function whose shifts form a Parseval frame. For a second countable locally compact abelian group $G$ we prove a useful Hilbert space isomorphism, introduce range funct...
متن کاملPhaseless Sampling and Reconstruction of Real-Valued Signals in Shift-Invariant Spaces
Sampling in shift-invariant spaces is a realistic model for signals with smooth spectrum. In this paper, we consider phaseless sampling and reconstruction of real-valued signals in a shift-invariant space from their magnitude measurements on the whole Euclidean space and from their phaseless samples taken on a discrete set with finite sampling density. We introduce an undirected graph to a sign...
متن کاملNonuniform Average Sampling and Reconstruction of Signals with Finite Rate of Innovation
From an average (ideal) sampling/reconstruction process, the question arises whether and how the original signal can be recovered from its average (ideal) samples. We consider the above question under the assumption that the original signal comes from a prototypical space modelling signals with finite rate of innovation, which includes finitely-generated shift-invariant spaces, twisted shift-in...
متن کاملTranslation Invariant Approach for Measuring Similarity of Signals
In many signal processing applications, an appropriate measure to compare two signals plays a fundamental role in both implementing the algorithm and evaluating its performance. Several techniques have been introduced in literature as similarity measures. However, the existing measures are often either impractical for some applications or they have unsatisfactory results in some other applicati...
