Active Eavesdropper Mitigation via Orthogonal Channel Estimation
Gian Marti, Christoph Studer
Beamforming is a powerful tool for physical layer security, as it can be used for steering signals towards legitimate receivers and away from eavesdroppers. An active eavesdropper,…
High Dynamic Range mmWave Massive MU-MIMO with Householder Reflections
Victoria Palhares, Gian Marti, Oscar Castañeda +1
All-digital massive multiuser (MU) multiple-input multiple-output (MIMO) at millimeter-wave (mmWave) frequencies is a promising technology for next-generation wireless systems. Low…
Single-Antenna Jammers in MIMO-OFDM Can Resemble Multi-Antenna Jammers
Gian Marti, Christoph Studer
In multiple-input multiple-output (MIMO) wireless systems with frequency-flat channels, a single-antenna jammer causes receive interference that is confined to a one-dimensional su…
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…
