چکیده
In this paper, we consider (random) sampling of signals concentrated on a bounded Corkscrew domain ? metric measure space, and reconstructing approximately from their (un)corrupted data taken set contained in ?. We establish weighted stability bi-Lipschitz type for scheme the reproducing kernel space. The provides weak robustness to scheme, however due nonconvexity signals, it does not imply unique signal reconstruction. From samples finite ?, propose an algorithm find approximations Random is where positions are randomly according probability distribution. Next show that, with high probability, can be reconstructed uncorrupted (or corrupted) at i.i.d. random drawn provided that size least order ?(?)ln?(?(?)), ?(?) Finally, demonstrate performance proposed original when procedure either large density or size.

Sampling in Reproducing Kernel Hilbert Space
An account of sampling in the setting of reproducing kernel spaces is given, the main point of which is to show that the sampling theory of Kluvánek, even though it is very general in some respects, is nevertheless a special case of the reproducing kernel theory. A Dictionary is provided as a handy summary of the essential steps. Starting with the classical formulation, the notion of band-limit...
متن کاملSampling and Reconstruction of Signals in a Reproducing Kernel Subspace of $L^p({\Bbb R}^d)$
In this paper, we consider sampling and reconstruction of signals in a reproducing kernel subspace of L(R), 1 ≤ p ≤ ∞, associated with an idempotent integral operator whose kernel has certain off-diagonal decay and regularity. The space of p-integrable non-uniform splines and the shift-invariant spaces generated by finitely many localized functions are our model examples of such reproducing ker...
متن کاملConvolution Sampling and Reconstruction of Signals in a Reproducing Kernel Subspace
We consider convolution sampling and reconstruction of signals in certain reproducing kernel subspaces of L, 1 ≤ p ≤ ∞. We show that signals in those subspaces could be stably reconstructed from their convolution samples taken on a relativelyseparated set with small gap. Exponential convergence and error estimates are established for the iterative approximation-projection reconstruction algorithm.

متن کاملSampling and Galerkin reconstruction in reproducing kernel spaces
In this paper, we consider sampling in a reproducing kernel subspace of L. We introduce a pre-reconstruction operator associated with a sampling scheme and propose a Galerkin reconstruction in general Banach space setting. We show that the proposed Galerkin method provides a quasi-optimal approximation, and the corresponding Galerkin equations could be solved by an iterative approximation-proje...
