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,…
Optimizing Antenna Coding for Pixel Antenna Empowered SISO-OFDM Systems
Tianrui Qiao, Shanpu Shen, Yijun Chen +1
This work investigates antenna coding optimization to enhance the channel capacity of single-input single-output orthogonal frequency division multiplexing (SISO-OFDM) systems empo…
Antenna Coding Optimization for Pixel Antenna Empowered MIMO Wireless Power Transfer
Yijun Chen, Shanpu Shen, Tianrui Qiao +3
We investigate antenna coding utilizing pixel antennas as a new degree of freedom for enhancing multiple-input multiple-output (MIMO) wireless power transfer (WPT) systems. The obj…
Channel Estimation and Passive Beamforming for Pixel-based Reconfigurable Intelligent Surfaces with Non-Separable State Response
Huayan Guo, Junhui Rao, Alex M. H. Wong +2
Pixel-based reconfigurable intelligent surfaces (RISs) employ a novel design to achieve high reflection gain at a lower hardware cost by eliminating the phase shifters used in trad…
