Spatial Limits of Fluid Antenna Systems
Amy S. Inwood, Peter J. Smith, Rajitha Senanayake +1
Continuous fluid antenna systems (CFASs) represent an upper bound on the spatial diversity performance of fluid antenna systems (FASs), achieved when antennas may be positioned any…
On the Distribution of Matched Filtering with Continuous Aperture Arrays
Amy S. Inwood, Abdulla Firag, Peter J. Smith +1
Continuous aperture arrays (CAPAs) provide a theoretical upper bound on the performance of densely packed antenna arrays, but their analysis is limited by the lack of closed-form s…
BER Analysis and Optimization for Continuous RIS-Enabled NOMA
Mahmoud AlaaEldin, Amy S. Inwood, Peter J. Smith +1
This letter investigates a novel uplink (UL) system that integrates power-domain non-orthogonal multiple access (PD-NOMA) with a continuous reconfigurable intelligent surface (CRIS…
Level Crossing Rate Analysis for Optimal Single-user RIS Systems
Amy S. Inwood, Peter J. Smith, Philippa A. Martin +1
We analyse the level crossing rate (LCR) of an uplink single-user (SU) reconfigurable intelligent surface (RIS) aided system. It is assumed that the RIS to base station (RIS-BS) ch…
Phase Selection and Analysis for Multi-frequency Multi-user RIS Systems Employing Subsurfaces in Correlated Ricean and Rayleigh Environments
Amy S. Inwood, Peter J. Smith, Philippa A. Martin +1
Phase selection design for reconfigurable intelligent surfaces (RISs) is a significant research challenge, as a closed-form optimal solution for a multi-user (MU) system is believe…
High SNR Probabilities of Continuous Fluid Antenna Systems in Ricean Environments
Amy S. Inwood, Peter J. Smith, Rajitha Senanayake +1
We consider a single-user (SU) continuous fluid antenna system (CFAS) employing matched filtering (MF) operating over a Ricean fading channel. Focusing on the upper tail of the rec…
