Advanced adaptive compensation system for free-space optical communications
(Universitat Politècnica de Catalunya, 2019-09-20)
Tesi
Accés obertMassive 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 ... -
Atmospheric compensation experiments on free-space optical coherent communication systems
(Universitat Politècnica de Catalunya, 2015-06-15)
Tesi
Accés obertIn the last years free-space optical communications systems for wireless links have been proposed, studied, and implemented mainly due to the higher bandwidth that this technology is able to provide. Still, radio frequency ... -
Cabecera analógica programable para agrupaciones ópticas enfasadas
(Universitat Politècnica de Catalunya, 2015-07-20)
Treball Final de Grau
Accés restringit per decisió de l'autorNowadays, optical fiber has become the main means of data transmission. However, there are applications where is not possible to use it for various reasons (physical impossibility, cost, design choice). In these cases the ... -
Digital coherent transceiver for optical communications: from design to implementation
(Universitat Politècnica de Catalunya, 2012-02)
Projecte Final de Màster Oficial
Accés obert[ANGLÈS] In this project we analyze the theoretical models of optical coherent communication systems as well as the front-end arquitectures used to implement them. Key concepts as balanced photo detection and quantum limit ... -
Electronics for Analog Signal Processing in an Optical Phased Array
(Universitat Politècnica de Catalunya, 2013-10-15)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorOptical free-space communication will be a key building block for future information systems. However, when the link includes part of the atmosphere, clear-air turbulence induces serious phase distortions and fading to the ... -
Hybrid testbed of a free-space laser communications system for atmospheric turbulence compensation
(Universitat Politècnica de Catalunya, 2016-07-27)
Treball Final de Grau
Accés restringit per decisió de l'autorIn the last few years free-space laser communications have become a feasible and high-bandwidth wireless alternative to fiber optic cabling and radio frequency (RF) systems due to its extremely robustness against interference ... -
Monitorització de stents mitjançant sondes al rang del GHz
(Universitat Politècnica de Catalunya, 2018-02-05)
Treball Final de Grau
Accés restringit per decisió de l'autorThe main aim of this work is to analyse the stent response using microwave-based spectrometry (MWS). We have also developed a model (phantom) that simulates the conditions of in vivo experimentation in order to begin with ...
