Spatially Consistent Air-to-Ground Channel Modeling and Simulation via 3D Shadow Projections
Evgenii Vinogradov, Aymen Fakhreddine, Abdul Saboor +2
We present an approach for spatially-consistent semi-deterministic Air-to-Ground (A2G) channel modeling in Unmanned Aerial Vehicle-assisted networks. We use efficient 3D building s…
Spatially Consistent Air-to-Ground Channel Modeling with Probabilistic LOS/NLOS Segmentation
Evgenii Vinogradov, Abdul Saboor, Zhuangzhuang Cui +1
In this paper, we present a spatially consistent A2G channel model based on probabilistic LOS/NLOS segmentation to parameterize the deterministic path loss and stochastic shadow fa…
Device-Free 3D Drone Localization in RIS-Assisted mmWave MIMO Networks
Jiguang He, Charles Vanwynsberghe, Hui Chen +2
In this paper, we investigate the potential of reconfigurable intelligent surfaces (RISs) in facilitating passive/device-free three-dimensional (3D) drone localization within exist…
RIS-Augmented Millimeter-Wave MIMO Systems for Passive Drone Detection
Jiguang He, Aymen Fakhreddine, George C. Alexandropoulos
In the past decade, the number of amateur drones is increasing, and this trend is expected to continue in the future. The security issues brought by abuse and misconduct of drones…
On the Detection of Non-Cooperative RISs: Scan B-Testing via Deep Support Vector Data Description
George Stamatelis, Panagiotis Gavriilidis, Aymen Fakhreddine +1
In this paper, we study the problem of promptly detecting the presence of non-cooperative activity from one or more Reconfigurable Intelligent Surfaces (RISs) with unknown characte…
