Expectation Propagation Line Spectral Estimation (1907.09094v1)
Published 22 Jul 2019 in cs.IT and math.IT
Abstract: 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.
