An Enhanced MNOMP for Line Spectrum Estimation and Detection
Yulin Jiang, Jiang Zhu, Fengzhong Qu, Yonina C. Eldar
Multisnapshot Newtonized orthogonal matching pursuit (MNOMP) incorporates Newton's method into OMP to avoid the off-grid issues, achieve high accuracy, high resolution and fast line spectrum estimation with multiple measurement vectors. It employs the generalized likelihood ratio…
