Estudio de sistemas de beamforming analógico-digitales

Abstract

En el presente proyecto se han estudiado y simulado sistemas que implementen técnicas propias del 5G. Debido a que el mundo de las comunicaciones móviles está en plena revolución con la instauración de esta nueva tecnología, la simulación del conjunto de métodos que lo permitirán se ha convertido en un amplio campo de estudio. Para ello, se han considerado sistemas basados en tres principios: "sistemas MIMO" que implementen "técnicas de Beamforming" para el uso de frecuencias portadoras del orden de las "ondas milimétricas". En primer lugar, se realiza una explicación del marco regulador actual y se exponen los conceptos básicos de los sistemas de comunicación móvil con el fin de presentar los elementos sobre los que se fundamentarán las simulaciones. En segundo lugar, se presentan las características de los diferentes sistemas simulados (sistemas SISO, SIMO, MISO y MIMO, siendo la simulación de estos últimos en modelos que emplean una red de conmutadores y desfasadores y en modelos de tipo ?Full Digital?, ?Full Analog? e ?Hybrid Analog-Digital?). Y a continuación se comentan los resultados adquiridos. Para terminar, se realiza un análisis del impacto socioeconómico y se presentan posibles futuras líneas de trabajo a partir de nuevos proyectos basados en la presente memoria.

En el present projecte s'han estudiat i simulat sistemes que implementen tècniques pròpies del 5G. Degut a que el món de les comunicacions mòbils està en plena revolució amb la instauració d'aquesta nova tecnologia, la simulació del conjunt de mètodes que ho permetran s'ha convertit en un ampli camp d'estudi. Per això, s'han considerat els sistemes basats en tres principis: "Sistemes MIMO" que implementen "tècniques de Beamforming" per a l'ús de freqüències portadores de l'ordre de les "ones mil·limètriques". En primer lloc, es realitza una explicació del marc regulador actual i s'exposen els conceptes bàsics dels sistemes de comunicació mòbil amb la finalitat de presentar els elements sobre els que es fonamentaran les simulacions. En segon lloc, es presenten les característiques dels diferents sistemes simulats (sistemes SISO, SIMO, MISO i MIMO, essent la simulació dels últims aplicada en models que utilitzen una xarxa de commutadors i desfasadors i en models de tipus "Full Digital", "Full Analog" i "Hybrid Analog-Digital"). I a continuació es comenten els resultats obtinguts. Per acabar, es realitza una anàlisi de l'impacte sicioeconòmic i es presenten possibles futures línies de treball a partir de projectes basats en la present memòria.

In this project it has been studied and simulated systems that implement techniques related to 5G technology. Due to the fact that mobile industry is in the middle of a revolution, in order to set it up, the simulation of new signal processing methods compounds a very vast investigation field. For this reason, the simulated systems are based on three topics: "MIMO systems" that implements "Beamforming techniques" using a "millimeter wave" carrier frequency. First of all, this project report explains the regulatory framework of 5G technology and expose basic concepts of mobile communication systems so that it presents the main aspects that will define the simulations. In the second place, it presents the common features of the simulated systems (systems as SISO, SIMO, MISO and MIMO, with MIMO models based on switches architecture and MIMO models with a "Full Digital", "Full Analog" and "Hybrid Analog-Digital" architecture). Then, it explains the results obtained. Finally, it analyzes the socioeconomic impact and it shows future possible lines of research for new projects on the basis of this thesis.
