FBMC-Based Random Access Signal Design and Detection for LEO Base Stations

Autor: Màrius Caus, Ana Isabel Pérez-Neira

Publikováno v: IEEE Transactions on Wireless Communications. 22:2156-2170

The integration of non-terrestrial networks into the 5G ecosystem is mainly driven by the possibility of provisioning service in remote areas. In this context, the advent of flying base stations at the low Earth orbit (LEO) will enable anywhere and a

Vertical characterization of fine and coarse dust particles during an intense Saharan dust outbreak over the Iberian Peninsula in springtime 2021

Publikováno v: Atmospheric Chemistry and Physics. 23:143-161

An intense and long-lasting Saharan dust outbreak crossed the Iberian Peninsula (IP) from the southwest (SW) to the northeast (NE) from 25 March until 7 April 2021. This work aims to assess the optical and mass contribution of both fine and coarse du

On the estimation of Tsallis entropy and a novel information measure based on its properties

Autor: Martí Espelt, Aniol, Cabrera Estanyol, Ferran de, Riba Sagarra, Jaume

This letter explores a plug-in estimator of second-order Tsallis entropy based on Kernel Density Estimation (KDE) and its implicit regularization process. First, it is shown that the expected value of the estimator corresponds to the entropy of an Ad

Characterization of Tajogaite volcanic plumes detected over the Iberian Peninsula from a set of satellite and ground-based remote sensing instrumentation

Three volcanic plumes were detected during the Tajogaite volcano eruptive activity (Canary Islands, Spain, September–December 2021) over the Iberian Peninsula. The spatiotemporal evolution of these events is characterised by combining passive satel
