The rise of third-party content providers and the introduction of numerous applications has been driving the growth of mobile data traffic in the past few years. In order to tackle this challenge, Mobile Network Operators ...
La tesis presenta un modelo no recursivo de sistemas no lineales (SNLS) basado en las series de fourier, estableciendo una comparación con el modelo de volterra en términos de coste computacional y diseño. <br/><br/>Del ...
Worldwide, the coherent technologies have revolutionized the optical communication systems, significantly increasing the capacity of the fiber channel owing to transmission of advanced modulation formats and effective ...
The emergence of very capable mobile terminals, e.g. smartphones or tablets, has dramatically increased the demand of wireless data traffic in recent years. Current growth forecasts elucidate that wireless communication ...
Over the last few decades, transistor miniaturization has enabled a tremendous increase in the processing capability of commercial electronic devices, which, combined with the reduction of production costs, has tremendously ...
In this thesis, we address specific efforts towards developing the precise aspect of ultrashort laser pulse measurement in the context of biomedical research. The motivation for pursuing these new developments was triggered ...
Esta Tesis se ha enmarcado en un proyecto financiado por la CICYT gracias al cual se adquirió un equipo portátil de espectroscopia Raman con fibra óptica. Esto determinó el objetivo inicial de esta investigación, que ...
(English) The thesis presents various contributions to the field of speaker recognition. In the first part of the thesis, the focus is on unsupervised methods for speaker recognition. This includes a method that uses Deep ...
Nowadays, especially with the upswing of neural networks, speech synthesis is almost totally data driven. The goal of this thesis is to provide methods for automatic and unsupervised learning from data for expressive speech ...
Aquesta tesi presenta un pla de millores des de les xarxes d'accés existents basades en coure a xarxes de fibra òptica fins la llar de segona generació basades en xarxes òptiques passives per enrutament de longitud ...
Current transport network owners are focused on offering services on top of the infrastructures they own, while end users have no control over them. Traditionally, this has been their business model, as the cost of building ...
The first part of this dissertation focuses on an analysis of the spatial context in semantic image segmentation. First, we review how spatial context has been tackled in the literature by local features and spatial ...
The objective of this dissertation is to study and develop techniques to decompose the speech signal into its two main components: voice source and vocal tract. Our main efforts are on the glottal pulse analysis and ...
This Thesis proposes the design and the optimization of a hybrid WDM/TDM PON at the L1 (PHY) and L2 (MAC) layers, in terms of minimum deployment cost and enhanced performance for Greenfield NGPON. The particular case of ...
We are surrounded by electronic devices that take advantage of wireless technologies, from our computer mice, which require little amounts of information, to our cellphones, which demand increasingly higher data rates. ...
The design of wireless sensors for operation embedded in a medium with high losses creates a series of additional constraints that should be taken into consideration at design stage to enhance sensor performance. In such ...
(English) The expeditious growth and development of Beyond-5G and 6G networks inaugurated a new sector in the research of cellular networking. Automation and scaling are now considered a necessity to cope with the anticipated ...
