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,…
An Aliasing-Free Hybrid Digital-Analog Polyphonic Synthesizer
Jonas Roth, Domenic Keller, Oscar Castañeda +1
Analog subtractive synthesizers are generally considered to provide superior sound quality compared to digital emulations. However, analog circuitry requires calibration and suffer…
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…
