Query: Expectation Propagation Line Spectral Estimation   Line spectral estimation (LSE) is a fundamental problem in signal processing
fields, as it arises in various fields such as radar signal processing and
communication fields. This paper develops expectation propagation (EP) based
LSE (EPLSE) method. The proposed method automatically estimates the model
order, noise variance, and can deal with the nonlinear measurements. Numerical
experiments show the excellent performance of EPLSE.
