Estimation of Spectral Lines Using Expectation Propagation

ICASSP 2024accepted

We consider the line spectral estimation (LSE) from general linear/nonlinear measurements obtained through a generalized linear model (GLM). This paper develops expectation propagation (EP) based LSE (EPLSE) method. The proposed method automatically estimates the model order, noise variance, and can…

A Unitary Transform Based Generalized Approximate Message Passing

Jiang Zhu, Xiangming Meng, Xupeng Lei, Qinghua Guo

ICASSP 2023accepted

We consider the problem of recovering an unknown signal from general nonlinear measurements obtained through a generalized linear model (GLM). Based on the unitary transform approximate message passing (UAMP) and expectation propagation, a unitary transform based generalized AMP (GUAMP) algorithm is…
