Hybrid Beamforming With Widely-Spaced-Array for Multi-User Cross-Near-and-Far-Field Communications

With multi-GHz bandwidth, Terahertz (THz) beamforming has drawn increasing attention in the sixth generation (6G) and beyond communications. Existing beamforming designs mainly focus on a compact antenna array where typical communication occurs in the far-field. However, in dense multi-user scenario...
