Near-Field Communications for Extremely Large-Scale MIMO: A Beamspace Perspective
Kangjian Chen, Chenhao Qi, Jingjia Huang +2
Extremely large-scale multiple-input multiple-output (XL-MIMO) is regarded as one of the key techniques to enhance the performance of future wireless communications. Different from…
Near-Field Multiuser Communications based on Sparse Arrays
Kangjian Chen, Chenhao Qi, Geoffrey Ye Li +1
This paper considers near-field multiuser communications based on sparse arrays (SAs). First, for the uniform SAs (USAs), we analyze the beam gains of channel steering vectors, whi…
Triple-Refined Hybrid-Field Beam Training for mmWave Extremely Large-Scale MIMO
Kangjian Chen, Chenhao Qi, Octavia A. Dobre +1
This paper investigates beam training for extremely large-scale multiple-input multiple-output systems. By considering both the near field and far field, a triple-refined hybrid-fi…
