Super-Resolution Limit of the ESPRIT Algorithm [PDF]
IEEE Transactions on Information Theory, 2020 The problem of imaging point objects can be formulated as estimation of an unknown atomic measure from its $M+1$ consecutive noisy Fourier coefficients. The standard resolution of this inverse problem is $1/M$ and super-resolution refers to the capability of resolving atoms at a higher resolution.
