Fluid Antenna System-Enabled Interference Alignment
Jialu Zheng, Quanzhong Li, Qi Zhang
Interference alignment is an efficient spectrum reuse scheme for multiuser wireless networks. In this letter, assuming no channel state information at the transmitters, we investig…
OFDM Enabled Over-the-Air Computation Systems with Two-Dimensional Fluid Antennas
Heyang Xiong, Quanzhong Li, Qi Zhang
Fluid antenna system (FAS) is able to exploit spatial degrees of freedom (DoFs) in wireless channels. In this letter, to exploit spatial DoFs in frequency-selective environments, w…
Average Secrecy Capacity Maximization of Rotatable Antenna-Assisted Secure Communications
Pengchuan Jiang, Quanzhong Li, Lifeng Mai +1
A rotatable antenna, which is able to dynamically adjust its deflection angle, is promising to achieve better physical layer security performance for wireless communications. In th…
XSema: A Novel Framework for Semantic Extraction of Cross-chain Transactions
Ziye Zheng, Jiajing Wu, Dan Lin +2
As the number of blockchain platforms continues to grow, the independence of these networks poses challenges for transferring assets and information across chains. Cross-chain brid…
