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.

Fast adaptive esprit algorithm [PDF]
IEEE/SP 13th Workshop on Statistical Signal Processing, 2005, 2005 The ESPRIT algorithm is a subspace-based high resolution method used in source localization and spectral analysis. It relies on the rotational invariance property of the signal subspace, and provides accurate estimates of the signal parameters. However, its main drawback is a high computational cost.

The influence of different PAST-based subspace trackers on DaPT parameter estimation [PDF]
Advances in Radio Science, 2012 In the context of parameter estimation, subspace-based methods like ESPRIT have become common. They require a subspace separation e.g. based on eigenvalue/-vector decomposition. In time-varying environments, this can be done by subspace trackers.
