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…
Alternating Projections Method for Joint Precoding and Peak-to-Average-Power Ratio Reduction
Sueda Taner, Christoph Studer
Orthogonal frequency-division multiplexing (OFDM) time-domain signals exhibit high peak-to-average (power) ratio (PAR), which requires linear radio-frequency chains to avoid an inc…
Mitigating Smart Jammers in MU-MIMO via Joint Channel Estimation and Data Detection
Gian Marti, Christoph Studer
Wireless systems must be resilient to jamming attacks. Existing mitigation methods require knowledge of the jammer's transmit characteristics. However, this knowledge may be diffic…
Feature Learning for Neural-Network-Based Positioning with Channel State Information
Emre Gönültaş, Sueda Taner, Howard Huang +1
Recent channel state information (CSI)-based positioning pipelines rely on deep neural networks (DNNs) in order to learn a mapping from estimated CSI to position. Since real-world…
Jammer Mitigation via Beam-Slicing for Low-Resolution mmWave Massive MU-MIMO
Gian Marti, Oscar Castañeda, Christoph Studer
Millimeter-wave (mmWave) massive multi-user multiple-input multiple-output (MU-MIMO) promises unprecedented data rates for next-generation wireless systems. To be practically viabl…
Hardware-Aware Beamspace Precoding for All-Digital mmWave Massive MU-MIMO
Emre Gönültaş, Sueda Taner, Alexandra Gallyas-Sanhueza +2
Massive multi-user multiple-input multiple-output (MU-MIMO) wireless systems operating at millimeter-wave (mmWave) frequencies enable simultaneous wideband data transmission to a l…
