Joint User Localization and Location Calibration of A Hybrid Reconfigurable Intelligent Surface
Reza Ghazalian, Hui Chen, George C. Alexandropoulos +3
The recent research in the emerging technology of reconfigurable intelligent surfaces (RISs) has identified its high potential for localization and sensing. However, to accurately…
Bi-Static Sensing for Near-Field RIS Localization
Reza Ghazalian, Kamran Keykhosravi, Hui Chen +2
We address the localization of a reconfigurable intelligent surface (RIS) for a single-input single-output multi-carrier system using bi-static sensing between a fixed transmitter…
Channel Model Mismatch Analysis for XL-MIMO Systems from a Localization Perspective
Hui Chen, Ahmed Elzanaty, Reza Ghazalian +3
Radio localization is applied in high-frequency (e.g., mmWave and THz) systems to support communication and to provide location-based services without extra infrastructure. {For so…
Mathematics of Sparsity and Entropy: Axioms, Core Functions and Sparse Recovery
Giancarlo Pastor, Inmaculada Mora-Jiménez, Riku Jäntti +1
Sparsity and entropy are pillar notions of modern theories in signal processing and information theory. However, there is no clear consensus among scientists on the characterizatio…
On the Aggregate Interference in Random CSMA/CA Networks: A Stochastic Geometry Approach
June Hwang, Jinho Choi, Riku Jantti +1
In this paper, we investigate the cumulative distribution function (CDF) of the aggregate interference in carrier sensing multiple access/collision avoidance (CSMA/CA) networks mea…
