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…
Channel Estimation and Analog Precoding for Pixel-based Fluid-Antenna-Assisted Multiuser MIMO-OFDM Systems
Huayan Guo, Jichen Zhang, Junhui Rao +2
Pixel-based fluid antennas provide enhanced multiplexing gains and quicker radiation pattern switching than traditional designs. However, this innovation introduces challenges for…
Turbocharging Fluid Antenna Multiple Access
Noor Waqar, Kai-Kit Wong, Chan-Byoung Chae +1
We revisit the massive connectivity challenge by considering the case where no CSI is available at the BS and no precoding is used. In this situation, inter-user interference (IUI)…
A First Look at the Performance Enhancement Potential of Fluid Reconfigurable Intelligent Surface
Abdelhamid Salem, Kai-Kit Wong, George Alexandropoulos +2
The fluid antenna concept represents shape-flexible and position-flexible antenna technologies designed to enhance wireless communication applications. In this paper, we apply this…
