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…
Max-Min Rate Fairness Optimization for Multi-User Pinching-Antenna NOMA Systems
Mahmoud AlaaEldin, Amy Inwood, Xidong Mu +1
Pinching-antenna systems (PASs) can overcome signal blockage by repositioning dielectric radiating elements, called pinching antennas (PAs), along meter-scale waveguides to create…
BER Analysis and Optimization of Pinching-Antenna-Based NOMA Communications
Mahmoud AlaaEldin, Amy S. Inwood, Xidong Mu +1
This paper presents the first bit error rate (BER) analysis of a pinching-antenna (PA)-based non-orthogonal multiple access (NOMA) communication system. The PA is assumed to be abl…
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…
Dimensional Scaling Laws for Continuous Fluid Antenna Systems
Peter J. Smith, Amy S. Inwood, Michail Matthaiou +1
Consider the signal-to-noise ratio (SNR) of a continuous fluid antenna system (CFAS) operating over a Rayleigh fading channel. In this paper, we extend traditional system assumptio…
