Popis:	In this paper the problem of blind super-resolution of sparse signals using arbitrary sampling scheme and atomic lift is discussed. After comprehensive description on blind superresolution problem, it is shown that using Prolate Spheroidal Wave Functions (PSWFs), it is possible to derive a new SemiDefinite Program (SDP) for the blind super-resolution problem. Unlike the previous results, the newly proposed SDP can localize spikes without magnitude recovery. Several numerical simulations were conducted to compare the performance of the proposed method with the recent related research. Comment: 5 pages, 4 figures
