Location-Based Timing Advance Estimation for 5G Integrated LEO Satellite Communications
Wenjin Wang, Tingting Chen, Rui Ding +3
Integrated satellite-terrestrial communications networks aim to exploit both the satellite and the ground mobile communications, thus providing genuine ubiquitous coverage. For 5G…
Semi-Passive 3D Positioning of Multiple RIS-Enabled Users
Kamran Keykhosravi, Musa Furkan Keskin, Satyam Dwivedi +2
Reconfigurable intelligent surfaces (RISs) are set to be a revolutionary technology in the 6th generation of wireless systems. In this work, we study the application of RIS in a mu…
3D Orientation Estimation with Multiple 5G mmWave Base Stations
Mohammad A. Nazari, Gonzalo Seco-Granados, Pontus Johannisson +1
We consider the problem of estimating the 3D orientation of a user, using the downlink mmWave signals received from multiple base stations. We show that the received signals from s…
Position Information from Single-Bounce Reflections
Anastasios Kakkavas, Mario H. Castañeda García, Gonzalo Seco-Granados +3
In the context of positioning a target with a single-anchor, this contribution focuses on the Fisher information about the position, orientation and clock offset of the target prov…
Power Allocation and Parameter Estimation for Multipath-based 5G Positioning
Anastasios Kakkavas, Henk Wymeersch, Gonzalo Seco-Granados +3
We consider a single-anchor multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) system with imperfectly synchronized transmitter (Tx) and receiv…
Detection of Replay Attacks to GNSS based on Partial Correlations and Authentication Data Unpredictability
Gonzalo Seco-Granados, David Gomez-Casco, Jose A. Lopez-Salcedo +1
Intentional interference, and in particular GNSS spoofing, is currently one of the most significant concerns of the Positioning, Navigation and Timing (PNT) community. With the ado…
