(English) The 5th generation of mobile communications has been designed to address the unstoppable demand of data bandwidth. However, it also gives support to a range of vertical industries with different Quality of Service ...
In the Control Engineering field, the so-called Robust Identification techniques deal with the problem of obtaining not only a nominal model of the plant, but also an estimate of the uncertainty associated to the nominal ...
Tradicionalment, les tècniques d'accés múltiple en sistemes de comunicacions multi-usuari han estat desenvolupades o bé orientades a la connexió o bé orientades al tràfic. En el primer cas, l'objectiu és establir tants ...
The aim of this thesis is to design and implement a new Grid Resource Management methodology, where non-massive resources owners would be able to share their resources and integrate human collaboration across multiple ...
(English) The rapid evolution in satellite navigation technology (GNSS) requires advanced prototyping tools for exploring new signals and developing innovative systems. Prototyping is essential in the design and development ...
En la actualidad se están realizando diversos esfuerzos para realizar la visión fu-turista de las redes de telecomunicación autogestionadas. La gestión basada en políticas ha sido reconocida como una herramienta potencial ...
Els avenços recents en tecnologia informàtica i processament de la parla i del llenguatge, entre altres, han fet possible que noves maneres de comunicació entre les persones i les màquines comencin a semblar factibles. ...
Los canales múltiple-entrada-múltiple-salida (MIMO) han sido ampliamente propuestos para superar los desvanecimientos aleatorios de canal en comunicaciones inalámbricas no selectivas en frecuencia. Basados en equipar tanto ...
L'activitat humana que té lloc en sales de reunions o aules d'ensenyament es veu reflectida en una rica varietat d'events acústics, ja siguin produïts pel cos humà o per objectes que les persones manegen. Per això, la ...
Automatic acoustic scene analysis is a complex task that involves several functionalities: detection (time), localization (space), separation, recognition, etc. This thesis focuses on both acoustic event detection (AED) ...
El acelerado crecimiento de las comunicaciones a través de plataformas de transmisión en banda ancha por vía alámbrica e inalámbrica, sumado al uso cada vez más extenso de modulaciones de amplitud no constante que, debido ...
Las demandas y expectativas de los usuarios y operadores móviles crecen sin parar y, consecuentemente, los nuevos estándares han incorporado tecnologías de acceso de radio cada vez más eficientes. Las especificaciones ...
Massive amounts of information are created daily in commercial fields like earth observation, that must be downloaded to earth ground stations in the short time of a satellite pass. Today, much of the collected information ...
Les Equacions Integrals superficials més importants són l'Equació de Camp Elèctric (EFIE), per a l'anàlisi de la dispersió electromagnètica d'objectes conductors perfectes (PEC), i la formulació Poggio–Miller–Chang–Harr ...
This work is the result of more than eight years during a bachelor thesis, a master thesis, and the Ph.D. thesis dedicated to the development of the Microwave Interferometric Reflectometer (MIR) instrument. It summarizes ...
The first part of the thesis focuses on the analysis of relevant factors to estimate the response time between satellite-based and in-situ soil moisture (SM) using a Dynamic Time Warping (DTW). DTW was applied to the SMOS ...
There is a lack on ocean dynamics understanding, and that lead oceanographers to the need of acquiring more reliable data to study ocean characteristics. Oceanographic measurements are difficult and expensive but essential ...
Ground deformation measurements can provide valuable information for minimization of associated loss and damage caused by natural and environmental hazards. As a kind of remote sensing technique, Persistent Scatterer ...
Current network infrastructures are supported on a layered model whereby heterogeneous data traffic can be seamlessly transported. In this architecture, where client/server relationships are established between adjacent ...
Since their inception, more than one century ago, electrical grids have played the role of a critical infrastructure. During the majority of this time, power systems have not faced radical changes. In contrast, over the ...
