Frequency-Position-Fluid Antenna Array and Beamforming for Ultra-dense Connectivity in Terahertz Wireless Systems
Heyin Shen, Chong Han, Jinhong Yuan
To support ultra-dense connectivity in terahertz (THz) communications, this paper proposes a dynamic frequency-position-fluid antenna (D-FPFA) architecture. Frequency-tunable local…
On the Characterization and Evaluation of Doppler Squint in Wideband ODDM Systems
Xuehan Wang, Jinhong Yuan, Jintao Wang +1
The recently proposed orthogonal delay-Doppler division multiplexing (ODDM) modulation has been demonstrated to enjoy excellent reliability over doubly-dispersive channels. However…
Hybrid Beamforming with Widely-spaced-array for Multi-user Cross-Near-and-Far-Field Communications
Heyin Shen, Yuhang Chen, Chong Han +1
With multi-GHz bandwidth, Terahertz (THz) beamforming has drawn increasing attention in the sixth generation (6G) and beyond communications. Existing beamforming designs mainly foc…
Delay Alignment Modulation with Hybrid Analog/Digital Beamforming for Millimeter Wave and Terahertz Communications
Jieni Zhang, Yong Zeng, Xiangbin Yu +4
For millimeter wave (mmWave) or Terahertz (THz) communications, by leveraging the high spatial resolution offered by large antenna arrays and the multi-path sparsity of mmWave/THz…
