Coexistence of 50 G TWDM with current PON infrastructures
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference lecture
Restricted access - publisher's policyThe feasibility of repurposing NG-PON2 WM for 50G TWDM PON is evaluated. The limited bandwidth and spectral requirements are analyzed. Simulation and experiments measure optical power penalty, sideband distortion, and ... -
Slice-aware resource allocation and admission control for smart factory wireless networks
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Restricted access - publisher's policyThe 5th generation (5G) and beyond network offers substantial promise as the ideal wireless technology to replace the existing inflexible wired connections in traditional factories of today. 5G network slicing allows for ... -
BeGREEN intelligent plane for AI-driven energy efficient O-RAN management
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Open AccessCellular networks are undergoing a revolutionary transform with the advent of O-RAN architectures and AI/ML solutions. O-RAN’s Non-Real-Time and Near-Real Time RAN Intelligent Controllers open the door to the implementation ... -
Multistatic SAR imaging and precise orbit determination synergies using geostationary telecommunication satellites
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference lecture
Restricted access - publisher's policyLow Earth Orbit (LEO) remote sensing missions present a main limitation regarding their revisit time of several days or weeks. They cannot provide continuous monitoring over the same area of the planet. The on-going studies ... -
Pushing the limits of zero-shot end-to-end speech translation
(Association for Computational Linguistics, 2024)
Conference report
Open AccessData scarcity and the modality gap between the speech and text modalities are two major obstacles of end-to-end Speech Translation (ST) systems, thus hindering their performance. Prior work has attempted to mitigate these ... -
Interferometric orbital tracking of SAR missions with large processing gain
(VDE-Verlag, 2021)
Conference report
Open AccessThe performance of a compact baseline interferometer for orbit observation of SAR missions is assessed. The proof of concept is carried out by tracking the non-cooperative ASTRA 1M satellite. A nominal slave-master baseline ... -
Evaluating the suitability of long document embeddings for classification tasks: a comparative analysis
(SciTePress, 2024)
Conference report
Open AccessLong documents pose a significant challenge for natural language processing (NLP), which requires high-quality embeddings. Despite the numerous approaches that encompass both deep learning and machine learning methodologies, ... -
Impact of near-field conditions on the performance of RIS-aided mmWave communication strategies
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Open AccessIn this paper, we consider a reconfigurable intelligent surface (RIS)-based transmitter operating in a high-frequency band that sends more symbols per channel use than the number of antennas at the receiver. For such a ... -
Fast ready-to-harvest cotton detection and classification with YOLOv8 in greenhouse crops
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Open AccessAutonomous robotic systems come as a new way of harvesting cotton, which is needed to preserve quality while reducing expenses, as opposed to traditional methods. New algorithmic solutions must be developed to detect cotton ... -
Phase noise reduction in continuous-variable quantum key distribution using digital filtering
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Restricted access - publisher's policyQuantum key distribution (QKD) enables information-theoretic-secure secret key exchange thanks to the laws of quantum mechanics. Since it can easily be incorporated into existing telecom networks, continuous-variable QKD ... -
Sources of temporal decorrelation in an agricultural scene and their effect on sub-daily sar coherence time series
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Open AccessData obtained during a ground-based SAR experiment and an associated field campaign have been exploited to study the rate and sources of decorrelation in an agricultural test site in the conditions of observation of a ... -
BSC-UPC at EmoSPeech-IberLEF2024: attention pooling for emotion recognition
(CEUR-WS.org, 2024)
Conference report
Open AccessThe domain of speech emotion recognition (SER) has persistently been a frontier within the landscape of machine learning. It is an active field that has been revolutionized in the last few decades and whose implementations ...
