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…
A Jammer-Mitigating 267 Mb/s 3.78 mm 583 mW 328 Multi-User MIMO Receiver in 22FDX
Florian Bucheli, Oscar Castañeda, Gian Marti +1
We present the first multi-user (MU) multiple-input multiple-output (MIMO) receiver ASIC that mitigates jamming attacks. The ASIC implements a recent nonlinear algorithm that perfo…
Fundamental Limits for Jammer-Resilient Communication in Finite-Resolution MIMO
Gian Marti, Alexander Stutz-Tirri, Christoph Studer
Spatial filtering based on multiple-input multiple-output (MIMO) processing is a powerful method for jammer mitigation. In principle, a MIMO receiver can null the interference of a…
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…
LoFi User Scheduling for Multiuser MIMO Wireless Systems
Alexandra Gallyas-Sanhueza, Gian Marti, Victoria Palhares +2
We propose new low-fidelity (LoFi) user equipment (UE) scheduling algorithms for multiuser multiple-input multiple-output (MIMO) wireless communication systems. The proposed method…
