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…
