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…
Distributed Self-allocated Time Slot Reuse: Multi-hop Communication in Rigid UAV Formations
Amelia Samandari, Andreas Willig, Barry Wu +1
Deployment of Unmanned Aerial Vehicles (UAVs) in autonomous formations necessitates accurate and timely communication of safety information. A communication protocol that supports…
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…
