Optimal digital filter selection for remote photoplethysmography (rPPG) signal conditioning
Remote photoplethysmography (rPPG) using camera-based imaging has shown excellent potential recently in vital signs monitoring due to its contactless nature. However, the optimum filter selection for pre-processing rPPG data in signal conditioning is still ...
IOP Publishing Ltd2023Federated Linear Bandit Learning via Over-the-air Computation
Yuning Jiang, Xin Liu, Ting Wang
In this paper, we investigate federated contextual linear bandit learning within a wireless system that comprises a server and multiple devices. Each device interacts with the environment, selects an action based on the received reward, and sends model upd ...
IEEE2023An Efficient Signal-to-noise Approximation for Eccentric Inspiraling Binaries
Eccentricity has emerged as a potentially useful tool for helping to identify the origin of black hole mergers. However, eccentric templates can be computationally very expensive owing to the large number of harmonics, making statistical analyses to distin ...
IOP Publishing Ltd2022Spike-Based Sensing and Communication for Highly Energy-Efficient Sensor Edge Nodes
Mihai Adrian Ionescu, Teodor Rosca
Highly energy-efficient wireless sensor nodes are a prerequisite for a sustainable operation of the Internet of things. Therefore, classical approaches for system design based on digital signal processing are not a viable solution, but system design has to ...
IEEE2022Sensitivity, Noise and Resolution in a B -Modified Foundry-Made ISFET with Miniaturized Reference Electrode for Wearable Point-of-Care Applications
Mihai Adrian Ionescu, Junrui Zhang, Francesco Bellando, Pierpaolo Palestri, Luca Selmi
Ion-sensitive field-effect transistors (ISFETs) form a high sensitivity and scalable class of sensors, compatible with advanced complementary metal-oxide semiconductor (CMOS) processes. Despite many previous demonstrations about their merits as low-power ...
2021An Ultra Low-Noise Micropower PPG Sensor
Nowadays, efficient and remote health monitoring is becoming increasingly important, given both the ageing of population and the combined action of an increase in obesity level and cardiovascular diseases. The healthcare industry is becoming more reliant o ...
EPFL2020Objective evaluation of static beamforming on the quality of speech in noise
Hervé Lissek, Gilles André Courtois, Vincent Pierre Olivier Grimaldi
Beamforming is commonly used in devices such as in hearing instruments (HI) with a view to reducing noise. It consists in focusing on audio signals arising from a prescribed steering direction while suppressing those coming from other directions. The effic ...
European Acoustics Association2018METHOD AND SYSTEM TO REDUCE NOISE IN PHASED-ARRAY SIGNALS FROM RECEIVERS LOCATED AT DIFFERENT LOCATIONS
Paul Hurley, Matthieu Martin Jean-André Simeoni, Nezihe Merve Gürel
The present invention is notably directed to a computerized method to reduce noise in phased- array signals from a set of receivers at different locations. Time-series are received from the receivers, which time-series form phased-array signals. The time-s ...
2017Bolometric detection of ferromagnetic resonance in YIG slab
Jean-Philippe Ansermet, Haiming Yu, Sa Tu, Marcin Bialek, Yao Zhang
The resistance of the Pt bar deposited on the YIG slab was monitored while the magnetic field was ramped through the ferromagnetic resonance with the YIG slab facing a coplanar waveguide resonator excited at 4.3 GHz excitation. The resistance change provid ...
Elsevier2017How does one compute the noise power to simulate real and complex GNSS signals?
Cyril Botteron, Jérôme Leclère
Simulation of GNSS signals is very important to test and validate algorithms. With some algorithms, such as acquisition or tracking, we do not need to simulate a realistic constellation with actual ranges, Doppler or navigation data. We can simply simulate ...
