Three-Dimensional Radio Localization: A Channel Charting-Based Approach
Phillip Stephan, Florian Euchner, Stephan ten Brink
Channel charting creates a low-dimensional representation of the radio environment in a self-supervised manner using manifold learning. Preserving relative spatial distances in the…
CSI Obfuscation: Single-Antenna Transmitters Can Not Hide from Adversarial Multi-Antenna Radio Localization Systems
Phillip Stephan, Florian Euchner, Stephan ten Brink
The ability of modern telecommunication systems to locate users and objects in the radio environment raises justified privacy concerns. To prevent unauthorized localization, single…
Passive Channel Charting: Locating Passive Targets using Wi-Fi Channel State Information
Florian Euchner, David Kellner, Phillip Stephan +1
We propose passive channel charting, an extension of channel charting to passive target localization. As in conventional channel charting, we follow a dimensionality reduction appr…
Uncertainty-Aware Dimensionality Reduction for Channel Charting with Geodesic Loss
Florian Euchner, Phillip Stephan, Stephan ten Brink
Channel Charting is a dimensionality reduction technique that learns to reconstruct a low-dimensional, physically interpretable map of the radio environment by taking advantage of…
Channel Charting-Based Channel Prediction on Real-World Distributed Massive MIMO CSI
Phillip Stephan, Florian Euchner, Stephan ten Brink
Distributed massive MIMO is considered a key advancement for improving the performance of next-generation wireless telecommunication systems. However, its efficacy in scenarios inv…
Leveraging the Doppler Effect for Channel Charting
Florian Euchner, Phillip Stephan, Stephan ten Brink
Channel Charting is a dimensionality reduction technique that reconstructs a map of the radio environment from similarity relationships found in channel state information. Distance…
Augmenting Channel Charting with Classical Wireless Source Localization Techniques
Florian Euchner, Phillip Stephan, Stephan ten Brink
Channel Charting aims to construct a map of the radio environment by leveraging similarity relationships found in high-dimensional channel state information. Although resulting cha…
Angle-Delay Profile-Based and Timestamp-Aided Dissimilarity Metrics for Channel Charting
Phillip Stephan, Florian Euchner, Stephan ten Brink
Channel charting is a self-supervised learning technique whose objective is to reconstruct a map of the radio environment, called channel chart, by taking advantage of similarity r…
Improving Triplet-Based Channel Charting on Distributed Massive MIMO Measurements
Florian Euchner, Phillip Stephan, Marc Gauger +2
The objective of channel charting is to learn a virtual map of the radio environment from high-dimensional CSI that is acquired by a multi-antenna wireless system. Since, in static…
Geometry-Based Phase and Time Synchronization for Multi-Antenna Channel Measurements
Florian Euchner, Phillip Stephan, Marc Gauger +1
Synchronization of transceiver chains is a major challenge in the practical realization of massive MIMO and especially distributed massive MIMO. While frequency synchronization is…
