Joint Frequency-Space Sparse Reconstruction for DOA Estimation under Coherent Sources and Amplitude-Phase Errors
Yutong Chen, Cong Zhou, Changsheng You +1
In this letter, we propose a joint frequency-space sparse reconstruction method for direction-of-arrival (DOA) estimation, which effectively addresses the issues arising from the e…
Super-resolution Wideband Beam Training for Near-field Communications with Ultra-low Overhead
Cong Zhou, Changsheng You, Shuo Shi +2
In this paper, we propose a super-resolution wideband beam training method for near-field communications, which is able to achieve ultra-low overhead. To this end, we first study t…
Mixed Near-field and Far-field Localization in Extremely Large-scale MIMO Systems
Cong Zhou, Changsheng You, Chao Zhou +2
In this paper, we study efficient \emph{mixed near-field and far-field} target localization methods in extremely large-scale multiple-input multiple-output (XL-MIMO) systems Compar…
Multi-beam Training for Near-field Communications in High-frequency Bands
Cong Zhou, Changsheng You, Zixuan Huang +4
In this paper, we study efficient multi-beam training design for near-field communications to reduce the beam training overhead of conventional single-beam training methods. In par…
