Stable super-resolution limit and smallest singular value of restricted Fourier matrices
Weilin Li, Wenjing Liao
We consider the inverse problem of recovering the locations and amplitudes of a collection of point sources represented as a discrete measure, given of its noisy low-frequenc…

Elementary error estimates for super-resolution de-noising
Weilin Li
This paper studies the problem of recovering a discrete complex measure on the torus from a finite number of corrupted Fourier samples. We assume the support of the unknown discret…
