Performance Limits of FRIS Systems in Nakagami- Fading
Masoud Khazaee, Felipe A. P. de Figueiredo, Rausley A. A. de Souza +4
Fluid reconfigurable intelligent surfaces (FRIS) have recently emerged as a promising technology for enhancing wireless link reliability through spatial decorrelation. However, the…
Enhanced Fluid Index Modulation for Integrated Data and Energy Transfer
Long Zhang, Yizhe Zhao, Halvin Yang +2
Integrated data and energy transfer (IDET) is a promising technique for supporting sustainable low-power wireless networks. To improve both communication reliability and energy tra…
Geometry-Structured Channel Reconstruction for Conventional and Fluid Antenna Systems: Bayesian Inference and Fundamental Limits
Zhentian Zhang, Kai-Kit Wong, Kaitao Meng +5
Accurate channel state information (CSI) acquisition is critical for exploiting the spatial flexibility of fluid antenna systems (FASs). However, port selection and transmission op…
Diffusion Fluid Antenna Systems for Resilient ISAC
Noor Waqar, Kai-Kit Wong, Chan-Byoung Chae +1
Most existing integrated sensing and communication (ISAC) studies focus on enabling a base station (BS) to support sensing and communication over shared resources through advanced…
Fast Fluid Antenna Multiple Access
Noor Waqar, Kai-Kit Wong, Chan-Byoung Chae +1
Fast fluid antenna multiple access (FAMA) is an idea that promises to overcome severe interference in massive access scenarios by reconfiguring the antenna's position at the receiv…
Stochastic Geometry Analysis of Uplink CUMA-Enabled Cellular Networks
Chenguang Rao, Kai-Kit Wong, Xusheng Zhu +3
Uplink cellular networks are interference-dominated but interference channel state information (CSI) is rarely available at scale. The emerging fluid antenna system (FAS) concept,…
