Irregular Sampling in Approximation Subspaces
ABSTRACT We describe the irregular sampling problem for discretetime finite signals belonging to Fourier and wavelet based linear and nonlinear approximation subspaces. The problem is expressed as a linear system of equations which can be solved directly or iteratively. The existence of the solution depends on the rank of the matrix associated to the system. The standard iterative algorithm for...
متن کاملTwo-channel sampling in wavelet subspaces
We develop two-channel sampling theory in the wavelet subspace V1 from the multi resolution analysis {Vj}j∈Z. Extending earlier results by G. G. Walter [11], W. Chen and S. Itoh [2] and Y. M. Hong et al [5] on the sampling theory in the wavelet or shift invariant spaces, we find a necessary and sufficient condition for two-channel sampling expansion formula to hold in V1. 1 Indroduction The cla...
متن کاملReconstruction of Functions in Spline Subspaces from Local Averages
In this paper, we study the reconstruction of functions in spline subspaces from local averages. We present an average sampling theorem for shift invariant subspaces generated by cardinal B-splines and give the optimal upper bound for the support length of averaging functions. Our result generalizes an earlier result by Aldroubi and Gröchenig.
متن کاملSampling Theorems for Multivariate Shift Invariant Subspaces ∗
Regular and irregular sampling theorems for multivariate shift invariant subspaces are studied. We give a characterization of regular points and an irregular sampling theorem, which covers many known results, e.g., Kadec’s 1/4-theorem. We show that some subspaces may not have a regular point. We also present a reconstruction algorithm which is slightly different from the known one but is more e...
متن کاملIrregular Sampling Theorems for Wavelet Subspaces
where f ( w ) is the Fourier transform of f ( t ) defined by f ( w ) = J, f ( t )e-*”*dt . Unfortunately it is not appropriate for nonband-limited signals. However if we let y = 2 m ~ , m € 2, this problem can be viewed as a special case of sampling in wavelet subspaces with p(t) = sin?rt/nt playing the role of scaling function of MRA {Vm = W ( ~ ( 2 ~ t n},},. Realizing these properties, Walte...
