چکیده
Let $$I=(a,b)\times (c,d)\subset {\mathbb R}_{+}^2$$ be an index set and let $$\{G_{\alpha }(x) \}_{\alpha \in I}$$ a collection of Gaussian functions, i.e. $$G_{\alpha = \exp (-\alpha _1 x_1^2 - \alpha _2 x_2^2)$$ , where $$\alpha (\alpha _1, _2) I, \, x (x_1, x_2) R}^2$$ . We present complete description the uniformly discrete sets $$\Lambda \subset such that every bandlimited signal f admits stable reconstruction from samples $$\{f *G_{\alpha } (\lambda )\}_{\lambda \Lambda }$$

Random Sampling of Bandlimited Functions
We consider the problem of random sampling for bandlimited functions. When can a bandlimited function f be recovered from randomly chosen samples f(xj), j ∈ J ⊂ N? We estimate the probability that a sampling inequality of the form A‖f‖ 2 ≤ ∑ j∈J |f(xj)| ≤ B‖f‖2 hold uniformly for all functions f ∈ L(R) with supp f̂ ⊆ [−1/2, 1/2] or for some subset of bandlimited functions. In contrast to discret...
متن کاملOn the sampling and recovery of bandlimited functions via scattered translates of the Gaussian
Let λ be a positive number, and let (xj : j ∈ Z) ⊂ R be a fixed Riesz-basis sequence, namely, (xj) is strictly increasing, and the set of functions {R ∋ t 7→ ej : j ∈ Z} is a Riesz basis (i.e., unconditional basis) for L2[−π,π]. Given a function f ∈ L2(R) whose Fourier transform is zero almost everywhere outside the interval [−π, π], there is a unique square-summable sequence (aj : j ∈ Z), depe...

Let (xn) ⊂ R d be a uniformly separated sequence which forms a Fourier frame for PWB2 , the space of square-integrable functions on R d whose Fourier transforms vanish outside the Euclidean unit ball B2. Given λ > 0 and f ∈ PWB2 , there is a unique sequence (aj) in l2 such that the function Iλ(f)(x) := X aje −λ‖x−xj‖ 2 2 , x∈R d , is continuous and square integrable on R, and satisfies the inte...
متن کاملSampling and Reconstruction of Bandlimited BMO-Functions
Functions of bounded mean oscillation (BMO) play an important role in complex function theory and harmonic analysis. In this paper a sampling theorem for bandlimited BMO-functions is derived for sampling points that are the zero sequence of some sine-type function. The class of sinetype functions is large and, in particular, contains the sine function, which corresponds to the special case of e...
متن کاملSampling of bandlimited functions on unions of shifted lattices
We consider Shannon sampling theory for sampling sets which are unions of shifted lattices. These sets are not necessarily periodic. A function f can be reconstructed from its samples provided the sampling set and the support of the Fourier transform of f satisfy certain compatibility conditions. While explicit reconstruction formulas are possible, it is most convenient to use a recursive algor...
