Maximum A Posteriori Direction-of-Arrival Estimation via Mixed-Integer Semidefinite Programming
Tianyi Liu, Frederic Matter, Alexander Sorg +3
We propose a joint sparse maximum a posteriori (MAP) estimator for DOA estimation from multiple snapshots, reformulated as a mixed-integer semidefinite program (MISDP). This enable…
Hybrid Downlink Beamforming with Outage Constraints under Imperfect CSI using Model-Driven Deep Learning
Lukas Schynol, Marius Pesavento
We consider energy-efficient multi-user hybrid downlink beamforming (BF) and power allocation under imperfect channel state information (CSI) and probabilistic outage constraints.…
Same Signal, Different Story: Demystifying Receiver Effects in Wi-Fi Channel State Information
Fabian Portner, Francesco Gringoli, Matthias Hollick +1
Wi-Fi sensing has emerged as a versatile tool for tasks such as localization, gesture recognition, and vital-sign monitoring, enabling applications from smart environments to perso…
Fast Reconfiguration of Liquid Crystal-RISs: Modeling and Algorithm Design
Mohamadreza Delbari, Robin Neuder, Alejandro Jiménez-Sáez +2
LC technology is a promising hardware solution for realizing extremely large RISs due to its advantages in cost-effectiveness, scalability, energy efficiency, and continuous phase…
FDR Control for Complex-Valued Data with Application in Single Snapshot Multi-Source Detection and DOA Estimation
Fabian Scheidt, Jasin Machkour, Michael Muma
False discovery rate (FDR) control is a popular approach for maintaining the integrity of statistical analyses, especially in high-dimensional data settings, where multiple compari…
Sensor Insoles: A Review
Bastian Latsch, Felix Herbst, Mark Suppelt +6
Plantar pressure measurement, or pedobarography, is an essential tool for analyzing human motion in healthy individuals and patients. Across the reviewed literature, sensor insoles…
