Modified oriented dihedral model for scattering characteristic description with PolSAR data
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-19)
Article
Accés obertDihedral is a common structure in polarimetric SAR images and can be found on many man-made targets. Many researchers have proposed different dihedral models, but the accuracy of these models is limited. In this case, the ... -
On the design of a network digital twin for the radio access network in 5G and beyond
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-20)
Article
Accés obertA Network Digital Twin (NDT) is a high-fidelity digital mirror of a real network. Given the increasing complexity of 5G and beyond networks, the use of an NDT becomes useful as a platform for testing configurations and ... -
An assessment of SAOCOM L-Band PolInSAR capabilities for canopy height estimation: A case study over managed forests in Argentina
(Institute of Electrical and Electronics Engineers (IEEE), 2024-02-07)
Article
Accés obertThis work presents the first results of canopy height mapping with L -Band SAOCOM data by means of Polarimetric SAR Interferometry (PolInSAR). For this study case, a colocated temporal series of SAOCOM fully polarimetric ... -
Wavefront-modified vector beams for THz cornea spectroscopy
(Optical Society of American (OSA), 2023-11-20)
Article
Accés obertTerahertz spectroscopy is a promising method to diagnose ocular diseases, where the cornea is typically imaged by Gaussian beams. However, the beam’s mismatch with the cornea’s spherical surface produces a 5-10 % error in ... -
Curved boundary integral method for electromagnetic fields
(Optical Society of American (OSA), 2023-12-11)
Article
Accés obertThe angular spectrum method is a rigorous method to synthesize near and far-field electromagnetic beams from planar field distributions. However, this limitation of planar surfaces has restricted its applicability to beams ... -
Quality control of Doppler spectra from a vertically pointing, S-band profiling radar
(American Meteorological Society, 2024-02-21)
Article
Accés restringit per política de l'editorialThis study describes a novel combination of methods to remove spurious spectral peaks, or “spurs,” from Doppler spectra produced by a vertically pointing, S-band radar. The University of Massachusetts S-band frequency-modulated, ... -
Land, jet stream, and other atmospheric effects on burned area estimation during the South Asian heatwave of 2022
(2024-04)
Article
Accés obertUnderstanding the key variables that characterise fire propagation is important for a better estimation of fire events and their impacts. This study uses machine learning combined with satellite remote sensing and atmospheric ... -
Minimum error entropy estimation under contaminated Gaussian noise
(Institute of Electrical and Electronics Engineers (IEEE), 2023-10-12)
Article
Accés obertIt is shown that Rényi's entropy of a Gaussian mixture with entropic index α∈(1,∞] is upper-bounded by the cluster with minimum variance. This basic idea leads to a clean worst-case formulation of the minimum error entropy ... -
Magnetoelectric dipole antenna framework supporting orbital angular momentum modes
(2024)
Article
Accés restringit per política de l'editorialThe ability to utilize resources to meet the need of growing diversity of communication services and user behavior marks the future of cognitive wireless communication systems. Cognitive wireless technologies for vehicular ... -

(Institute of Electrical and Electronics Engineers (IEEE), 2024-03-01)
Article
Accés obertPolarization encoded Quantum Key Distribution (QKD) is attracting great attention as it generates unlimitedly and unconditionally secure keys for different use cases. Despite its theoretical excellence based on quantum ... -
LUT-free carrier recovery for intradyne optical DPSK receivers in udWDM-PON
(Institute of Electrical and Electronics Engineers (IEEE), 2019-03-15)
Article
Accés obertWe present a lookup table (LUT)-free carrier recovery architecture for intradyne optical DPSK receivers that reduce the required digital signal processing hardware resources, power consumption as well as total process ... -
Quantum transport of high-dimensional spatial information with a nonlinear detector
(2023-12-13)
Article
Accés obertInformation exchange between two distant parties, where information is shared without physically transporting it, is a crucial resource in future quantum networks. Doing so with high-dimensional states offers the promise ...
