Near-Field Beam Management for Extremely Large-Scale Array Communications
Changsheng You, Yunpu Zhang, Chenyu Wu +5
Extremely large-scale arrays (XL-arrays) have emerged as a promising technology to achieve super-high spectral efficiency and spatial resolution in future wireless systems. The lar…
Mixed Near- and Far-Field Communications for Extremely Large-Scale Array: An Interference Perspective
Yunpu Zhang, Changsheng You, Li Chen +1
Extremely large-scale array (XL-array) is envisioned to achieve super-high spectral efficiency in future wireless networks. Different from the existing works that mostly focus on t…
Cramér-Rao Bounds of Near-Field Positioning Based on Electromagnetic Propagation Model
Ang Chen, Li Chen, Yunfei Chen +3
The adoption of large-scale antenna arrays at high-frequency bands is widely envisioned in the beyond 5G wireless networks. This leads to the near-field regime where the wavefront…
Hierarchical-Absolute Reciprocity Calibration for Millimeter-wave Hybrid Beamforming Systems
Li Chen, Rongjiang Nie, Yunfei Chen +1
In time-division duplexing (TDD) millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems, the reciprocity mismatch severely degrades the performance of the h…
