Learned Blockwise Port Activation for Real Time Beamforming in Fluid Antenna Arrays
Yuanhui Wu, Zhentian Zhang, Hanjiang Hong +5
Fluid antenna arrays (FAAs), support multiuser downlink transmission by activating a subset of reconfigurable ports. The activation mask jointly determines the effective channel an…
HARQ for Slow Fluid Antenna Multiple Access
Sixu Han, Kai-Kit Wong, Hanjiang Hong +1
Slow fluid antenna multiple access (sFAMA), enabled by the fluid antenna system (FAS), has recently emerged as a practical and low-complexity paradigm for supporting massive wirele…
Spatial Modulation for Tx-SIMO-FAS: Port Selection and Performance Analysis
Xusheng Zhu, Kai-Kit Wong, Hanjiang Hong +2
This paper considers a single-input multiple-output (SIMO) setup with a fluid antenna system (FAS) at the transmitter side and multiple fixed antennas at the receiver, which is ref…
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,…
Phased Ultra Massive Array (PUMA)
Hanjiang Hong, Kai-Kit Wong, Xusheng Zhu +3
This paper proposes a novel multiple-access framework, termed the phased ultra massive antenna array (PUMA), which exploits the distinctive spatial flexibility of fluid antenna sys…
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…
