Towards a Connected Heterogeneous All-Medium Integrated Network (CHAIN) for Converged Connectivity Across Land, Sea, Air, and Space
Paul Anthony Haigh, Sujan Rajbhandari, Kyle Bottrill +12
Next-generation connectivity depends on data traversing multiple physical media within a single end-to-end path, yet research in optical fibre, free-space optical and radio wireles…
Non-Uniform Antenna Array Design with Large Inter-Element Spacing for Massive MIMO
Lin Chen, Qu Luo, Orestis Christogeorgos +5
In massive multiple-input multiple-output (MIMO) systems, uniform arrays are typically configured with inter-element spacing no greater than half a wavelength to avoid grating lobe…
Topological Winding Readout of an Emergent Page-Wootters Clock
Hesam Zaravashan, Gabriele Gradoni, Mohsen Khalily
The Page--Wootters construction gives time a Hilbert space, representing it as an internal degree of freedom whose readings the rest of the system evolves with respect to. We ask w…
Joint Beamforming and Position Optimization for FIRES-NOMA Assisted Wireless Communication Systems
Yu Liu, Qu Luo, Gaojie Chen +4
To address the limitations of conventional reconfigurable intelligent surfaces (RIS) in spatial control capability, this paper proposes a fluid integrated reflecting and emitting s…
An Overview of Electromagnetic Illusions: Empowering Smart Environments with Reconfigurable Metasurfaces
Hamidreza Taghvaee, Mohsen Khalily, Gabriele Gradoni +1
This study delves into the innovative landscape of metasurfaces, with a particular focus on their role in achieving EM illusion (EMI) a facet of paramount significance. The control…
A Novel Transmission Policy for Intelligent Reflecting Surface Assisted Wireless Powered Sensor Networks
Zheng Chu, Pei Xiao, De Mi +3
This paper proposes a novel transmission policy for an intelligent reflecting surface (IRS) assisted wireless powered sensor network (WPSN). An IRS is deployed to enhance the perfo…
Evaluation of Low Complexity Massive MIMO Techniques Under Realistic Channel Conditions
Manijeh Bashar, Alister G. Burr, Katsuyuki Haneda +4
A low complexity massive multiple-input multiple-output (MIMO) technique is studied with a geometry-based stochastic channel model, called COST 2100 model. We propose to exploit th…
