Experimental measurements of radio signal attenuation and Faraday rotation due to electron number density in a plasma flow
(European Conference for AeroSpace Sciences (EUCASS), 2023)
Text en actes de congrés
Accés obertSpacecraft entering a planetary atmosphere are surrounded by a plasma layer containing high levels of ionization. The high electron number densities cause attenuation and rotation of the polarization of the emitted signal, ... -
Realistic colon phantoms for microwave colonoscopy validation
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Comunicació de congrés
Accés obertColon phantoms that replicate a real colon dielectric properties, shape, and texture are required to verify a microwave colonoscopy system. The realism and accuracy of the phantom are quantified in this study using a method ... -
Frequency modulation aggregation for federated learning
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertFederated edge learning (FEEL) is a framework for training models in a distributed fashion using edge devices and a server that coordinates the learning process. In FEEL, edge devices periodically transmit model parameters ... -
Efficient onboard band selection algorithm for hyperspectral imagery in SmallSat missions with limited downlink capabilities
(Institute of Electrical and Electronics Engineers (IEEE), 2024-04-09)
Article
Accés obertHyperspectral imaging is a key tool in numerous remote sensing applications. Images with tens or even hundreds of spectral bands contain a wealth of information to retrieve multiple geophysical parameters, to perform target ... -
Fengyun-2F/VISSR land surface temperature anomalies between 2014 and 2022 and their potential correlation with earthquakes
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Comunicació de congrés
Accés obertFrom 1998 to 2022, Earthquakes have caused more than 850 thousand deaths and US$ 700 billion in economic losses. At this time, there is no reliable precursor to predict them. Many studies have attempted to link Land Surface ... -
Deployable Fresnel Zone Plate antenna for CubeSats
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertEarth observation satellite missions are becoming increasingly important and have been also boosted by the appearance of small satellites, affordable to small companies and universities. Technology miniaturization and the ... -
Radio frequency signal propagation through a stagnant flow in a plasma facility for analysis of the communication blackout phenomenon
(2024)
Text en actes de congrés
Accés obertDuring the atmospheric entry phase, the high levels of ionization on the plasma layer around a spacecraft can cause disruption of the communications, leading to a radio blackout phenomenon. This work, as part of the Horizon ... -
Direct connection of uni-traveling-carrier photodiodes to antennas for frequency reconfigurable fiber-radio transmission in the Ka band
(2024-07-01)
Article
Accés obertA compact photonically-driven wireless emitter based on a Uni-Traveling-Carrier photodiode (UTC-PD) which directly connects to a short asymmetrical inductive dipole (SAID) antenna is presented. The design exploits the ... -
GPU versus FPGA implementation of a digital predistortion linearizer for wideband radiofrequency power amplifiers
(Elsevier, 2024-01)
Article
Accés obertThis paper presents and compares the implementation of a digital predistortion (DPD) linearizer for radiofrequency power amplifiers (PAs) considering two different hardware acceleration platforms. Both graphics processing ... -
Association of land surface temperature anomalies from GOES/ABI, MSG/SEVIRI, and Himawari-8/AHI with land earthquakes between 2010 and 2021
(Taylor & Francis Group, 2024-04-09)
Article
Accés obertEvery year, earthquakes cause numerous casualties and billions of dollars in economic damages, and so far, it is impossible to pre-dict them. Many researchers have studied the land surface tem-perature (LST) anomalies ... -
On the correlation between earthquakes and prior ionospheric scintillations over the ocean: a study using GNSS-R data between 2017 and 2021
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-01)
Article
Accés obertFrom 1980 to 2021, earthquakes have caused more than 846 000 casualties and about US$ 661 billion in economic losses. At present, there are no reliable earthquake precursors to generate alerts. Currently, the link between ... -
LoRa modulation for split learning
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertIn this paper we introduce a task-oriented communication design for split learning (SL) over a communication channel. Our approach involves the Expressive Neural Network (ENN), a novel neural network featuring adaptive ...
