Joint Active User Detection, Channel Estimation, and Data Detection for Massive Grant-Free Transmission in Cell-Free Systems
Gangle Sun, Mengyao Cao, Wenjin Wang +2
Cell-free communication has the potential to significantly improve grant-free transmission in massive machine-type communication, wherein multiple access points jointly serve a lar…
Channel Charting in Real-World Coordinates
Sueda Taner, Victoria Palhares, Christoph Studer
Channel charting is an emerging self-supervised method that maps channel state information (CSI) to a low-dimensional latent space, which represents pseudo-positions of user equipm…
Universal MIMO Jammer Mitigation via Secret Temporal Subspace Embeddings
Gian Marti, Christoph Studer
MIMO processing enables jammer mitigation through spatial filtering, provided that the receiver knows the spatial signature of the jammer interference. Estimating this signature is…
Wireless Channel Charting: Theory, Practice, and Applications
Paul Ferrand, Maxime Guillaud, Christoph Studer +1
Channel charting is a recently proposed framework that applies dimensionality reduction to channel state information (CSI) in wireless systems with the goal of associating a pseudo…
