CSI Reconstruction in Fluid Antenna Systems Without Spatial Covariance Priors
Zhentian Zhang, Kaitao Meng, Tuo Wu +6
Fluid antenna systems (FASs) exploit many candidate ports for spatial diversity, but hardware constraints allow channel observations at only a few active ports. Whether full-port C…
Artificial Noise Versus Artificial Noise Elimination: Redefining Scaling Laws of Physical Layer Security
Hong Niu, Tuo Wu, Xia Lei +4
Artificial noise (AN) is a key physical-layer security scheme for wireless communications over multiple-input multiple-output wiretap channels. Recently, artificial noise eliminati…
UAV-Enabled Short-Packet Communication via Fluid Antenna Systems
Xusheng Zhu, Kai-Kit Wong, Hanjiang Hong +4
This paper develops a framework for analyzing UAV-enabled short-packet communication, leveraging fluid antenna system (FAS)-assisted relaying networks. Operating in the short-packe…
Fluid Antenna System-Enabled UAV Communications in the Finite Blocklength Regime
Xusheng Zhu, Kai-Kit Wong, Hanjiang Hong +4
This paper develops a comprehensive framework for the performance analysis of fluid antenna system (FAS)-enabled unmanned aerial vehicle (UAV) relaying networks operating in the fi…
On the Fundamental Scaling Laws of Fluid Antenna Systems
Xusheng Zhu, Farshad Rostami Ghadi, Tuo Wu +3
Fluid antenna systems (FAS) offer a promising paradigm for enhancing wireless communication by exploiting spatial diversity, yet a rigorous analytical framework for their error pro…
