On the Probability of Network States with Gaussian Connectivity Functions
Amy S. Inwood, Peter J. Smith, Pawel Dmochowski +3
In this paper, we consider the connectivity of a random network of N mobile devices in three dimensions (3D), where the location of each device or node has a Gaussian distribution…
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…
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
Amy S. Inwood, Peter J. Smith, Philippa A. Martin +1
In this paper, we analyse the performance of a reconfigurable intelligent surface (RIS) aided system where the RIS is divided into subsurfaces. Each subsurface is designed specific…
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…
Second Order Channel Statistics: An Analysis for Optimal Single-user RIS Systems
Amy S. Inwood, Peter J. Smith, Philippa A. Martin +1
A key challenge facing reconfigurable intelligent surfaces (RISs) is channel state information acquisition. Passive RISs cannot generate pilot signals or process data, making rapid…
Performance Characterization of Continuous Reconfigurable Intelligent Surfaces
Amy S. Inwood, Peter J. Smith, Mahmoud AlaaEldin +1
We consider a reconfigurable intelligent surface (RIS) that can implement a phase rotation continuously over the whole surface rather than via a finite number of discrete elements.…
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…
