Near-Field Channel Estimation and Joint Angle-Range Recovery in XL-MIMO Systems: A Gridless Super-Resolution Approach
Feng Xi, Dehui Yang
Existing near-field channel estimation methods for extremely large-scale MIMO (XL-MIMO) typically discretize angle and range parameters jointly, resulting in large polar-domain cod…

Gridless Chirp Parameter Retrieval via Constrained Two-Dimensional Atomic Norm Minimization
Dehui Yang, Feng Xi
This paper is concerned with the fundamental problem of estimating chirp parameters from a mixture of linear chirp signals. Unlike most previous methods, which solve the problem by…
