Near-Field Dual-UPA Communications: A Generalized Geometric Approach
Li Zheng, Xing Hao, Ziru Chen +3
This paper investigates a near-field (NF) multiple-input multiple-output (MIMO) communication system equipped with dual uniform planar arrays (UPAs). We first develop a generalized…

Low-complexity Design for Beam Coverage in Near-field and Far-field: A Fourier Transform Approach
Chao Zhou, Changsheng You, Cong Zhou +3
In this paper, we study efficient beam coverage design for multi-antenna systems in both far-field and near-field cases. To reduce the computational complexity of existing sampling…
