Forward-Backward Atomic Norm for Spectral Super-Resolution

IEEE SAM 2020: Special Sessions > Aperture Extension and Synthetic Techniques for High-Resolution Detection and Estimation

A well-known fact in line spectral estimation (LSE) is that the complex conjugated backward data sequence is composed of the same frequency components as the original data sequence. In this paper, this fact is utilized to develop a forward-backward atomic norm method for LSE within the spectral super-resolution framework. It is shown theoretically that the proposed forward-backward method is superior to the previous, standard one.
