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…
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…
Optimal Phase Design for RIS Channel Estimation
Chelsea L. Miller, Peter J. Smith, Pawel A. Dmochowski
We develop an optimal version of a prior two-stage channel estimation protocol for RIS-assisted channels. The new design uses a modified DFT matrix (MDFT) for the training phases a…
Efficient Optimization Techniques for RIS-aided Wireless Systems
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski +1
The objective of this paper is to develop simple techniques to enhance the performance of multi-user RIS aided wireless systems. Specifically, we develop a novel technique called \…
Phase Dependent Loss Analysis for RIS Systems
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski
In this paper we focus on phase dependent loss (PDL), an important aspect of reconfigurable intelligent surfaces (RIS) where the signals reflected from the RIS elements are attenua…
Optimal SNR Analysis for Single-user RIS Systems in Ricean and Rayleigh Environments
Ikram Singh, Peter J. Smith, Pawel A. Dmochowski
We present an analysis of the optimal uplink (UL) SNR of a SIMO Reconfigurable Intelligent Surface (RIS)-aided wireless link. We assume that the channel between base station (BS) a…
