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…
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…
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…
The Impact of SAR-ADC Mismatch on Quantized Massive MU-MIMO Systems
Jérémy Guichemerre, Christoph Studer
Low-resolution analog-to-digital converters (ADCs) in massive multi-user (MU) multiple-input multiple-output (MIMO) wireless systems can significantly reduce the power, cost, and i…
