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…
