Physical Layer Authentication Using Information Reconciliation

no code implementations19 Apr 2024 Atsu Kokuvi Angélo Passah, Rodrigo C. de Lamare, Arsenia Chorti

Furthermore, the computational complexity of classical cryptographic approaches based on public key distribution can be a limiting factor for using in simple, low-end Internet of things (IoT) devices.

State Machine-based Waveforms for Channels With 1-Bit Quantization and Oversampling With Time-Instance Zero-Crossing Modulation

no code implementations28 Jan 2023 Diana M. V. Melo, Lukas T. N. Landau, Rodrigo C. de Lamare

In this work, we propose a practical waveform design based on the established TI ZX modulation for a multiuser multi-input multi-output (MIMO) downlink scenario with 1-bit quantization and temporal oversampling at the receivers.

Multiuser-MIMO Systems Using Comparator Network-Aided Receivers With 1-Bit Quantization

no code implementations18 Nov 2022 Ana Beatriz L. B. Fernandes, Zhichao Shao, Lukas T. N. Landau, Rodrigo C. de Lamare

We propose low-resolution multiuser MIMO receivers where the signals are simultaneously processed by 1-bit ADCs and a comparator network, which can be interpreted as additional virtual channels with binary outputs.

Study of Robust Adaptive Beamforming Based on Low-Complexity DFT Spatial Sampling

no code implementations23 Jun 2021 Saeed Mohammadzadeh, Vitor H. Nascimento, Rodrigo C. de Lamare, Osman Kukrer

The DFT coefficients corresponding to the angles within the noise-plus-interference region are used to reconstruct the noise-plus-interference covariance matrix (NPICM), while the desired signal covariance matrix (DSCM) is estimated by identifying and removing the noise-plus-interference component from the SCM.
