Sparse MIMO-OFDM Channel Estimation via RKHS Regularization
James Delfeld, Gian Marti, Chris Dick
We propose a method for channel estimation in multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) wireless communication systems. The method exp…
Joint Jammer Mitigation and Data Detection
Gian Marti, Christoph Studer
Multi-antenna (or MIMO) processing is a promising solution to the problem of jammer mitigation. Existing methods mitigate the jammer based on an estimate of its spatial signature t…
GNSS Jammer and Spoofer Mitigation via Multi-Antenna Processing
Jonas Elmiger, Gian Marti, Christoph Studer
Modern positioning relies on radio signals from global navigation satellite systems (GNSS). Their low receive power renders these radio signals susceptible to jamming attacks, in w…
Universal MIMO Jammer Mitigation
Gian Marti, Christoph Studer
Multi-antenna processing enables jammer mitigation through spatial filtering, provided that the receiver knows the spatial signature of the jammer interference. Estimating this sig…
PyJama: Differentiable Jamming and Anti-Jamming with NVIDIA Sionna
Fabian Ulbricht, Gian Marti, Reinhard Wiesmayr +1
Despite extensive research on jamming attacks on wireless communication systems, the potential of machine learning for amplifying the threat of such attacks, or our ability to miti…
Accurate Direct Positioning in Distributed MIMO Using Delay-Doppler Channel Measurements
Benjamin J. B. Deutschmann, Christian Nelson, Mikael Henriksson +5
Distributed multiple-input multiple-output (D-MIMO) is a promising technology for simultaneous communication and positioning. However, phase synchronization between multiple access…
Jammer-Resilient Time Synchronization in the MIMO Uplink
Gian Marti, Flurin Arquint, Christoph Studer
Spatial filtering based on multiple-input multiple-output (MIMO) processing is a promising approach to jammer mitigation. Effective MIMO data detectors that mitigate smart jammers…
