Nonlinear Approximation by Sums of Exponentials and Translates
In this paper, we discuss the numerical solution of two nonlinear approximation problems. Many applications in electrical engineering, signal processing, and mathematical physics lead to the following problem. Let h be a linear combination of exponentials with real frequencies. Determine all frequencies, all coefficients, and the number of summands if finitely many perturbed, uniformly sampled ...
متن کاملNonlinear approximation by sums of nonincreasing exponentials
Many applications in electrical engineering, signal processing, and mathematical physics lead to following approximation problem: Let h be a short linear combination of nonincreasing exponentials with complex exponents. Determine all exponents, all coefficients, and the number of summands from finitely many equispaced sampled data of h. This is a nonlinear inverse problem. This paper is an exte...
متن کاملOn approximation by exponentials
We consider an approximation of L 2 0; 1) functions by linear combinations of exponentials fexp(? ` t)g. Having derived explicitly by Fourier transform techniques an orthogonal basis of exponentials, we specialize the discussion to the choicè = q ` , ` = 0; 1; : : :, where q 2 (0; 1). In that case the underlying orthogonal functions possess a particularly appealing form and they obey interestin...
متن کاملApproximation by Piecewise Exponentials *
A function is called an exponential if it is a linear combination of products of polynomials with pure exponentials. In this paper lower and upper bounds for families of spaces of piecewise exponentials are established. In particular, the exact Lp-approximation order (1 _< p _<) is found for a family {Sh}h>O of function spaces when each Sh is generated by an exponential box spline and its multi...
متن کاملNonlinear Approximation of Functions by Sums of Wave Packets∗
We consider the problem of approximating functions by sums of wave packets. Our objective is to find sparse decompositions of image functions, over a finite range of scales. We also address the naturally connected task of approximating the wavefront set, computationally. We formulate the problem in terms of Hankel operators, Hankel matrices and their low-rank approximations, and develop an alge...
