“…Multi-gigabit wireless over optical fiber networks using the radioover-Fiber (RoF) technique have emerged as a powerful solution for increasing system capacity and mobility, as well as reducing the cost of access networks [1][2][3][4][5]. Nowadays, peer-to-peer (P2P) communication between wireless users in RoF access networks is increasingly useful due to the growth of applications such as multimedia communications, and voice and video over IP [6].…”

Abstract-A novel peer-to-peer (P2P) interconnection architecture in a 60-GHz millimeter-wave (mm-wave) radio-over-fiber (RoF) access network is proposed for the first time. In this scheme, the beating of the lightwaves for downlink and P2P transmissions at the photodiode (PD) can provide signal up-conversion for both signals. Phase noise and frequency instability between the two independent lightwaves can be eliminated by a self-heterodyned radio frequency (RF) receiver (envelope detector) located on the user terminal, which can also downconvert simultaneously the two mm-wave signals to their associated intermediate frequencies. No high-frequency clock sources or other high bandwidth devices are required for signal up/down-conversions. A proof-of-concept experimental demonstration has also been carried out. Error-free transmission of the 1-Gb/ signals is achieved over 50-km fiber (downlink) or 25-km fiber (P2P) plus 4-m air link.

“…There are both commercial as well as military applications of this technology. Commercial applications include broad-band signal distribution of interactive multimedia services to the home [4,5] and personal radio communication [6]. Examples of military application are Doppler radar [7] and phased array antennas [7].…”

“…La transparencia y la flexibilidad son características de los sistemas RoF, por lo que se las considera una excelente herramienta para afrontar el desarrollo y evolución de las redes de acceso y facilitar el acceso inalámbrico de elevado régimen binario de forma flexible, muy versátil y con bajo coste [Oga92], [Wak02a]. Los sistemas RoF centralizan la generación y control de las señales de radiofrecuencia a transmitir mediante fibra óptica hacia antenas remotas o puntos de acceso inalámbricos, para su posterior acceso según la tecnología radio empleada.…”

“…Para conseguirlo, se actúa sobre diferentes parámetros del modulador MZM, desde la forma de la de RF moduladora ó parámetros constructivos del modulador como la longitud de sus electrodos. Las técnicas de linealización se pueden clasificar en tres grandes grupos según los parámetros modificados: (i) técnicas de linealización eléctrica que actúan sobre la señal RF [Naz93], [Chi99], (ii) técnicas de linealización mediante post-procesado de la señal modulada [Hel00] y (iii) técnicas de linealización todo ópticas que proponen cambios en la estructura interna y en parámetros físicos u ópticos [Kor90], [Oga92], [Bet94], [Shi00].…”

IVPersonal Area Network). L'objectiu d'aquest estudi és obtenir màrges de seguretat per a garantir la interoperatibilitat d'ambdues tecnologies ràdio, els quals es poden aplicar en el futur desenvolupament de tècniques avançades de mitigació de la interferència com detecció i exclusió (DAA, Detect-and-Avoid), dins de futures aplicacions com les anomenades cognitive radio.Després, s'estudia la coexistència de MB-OFDM UWB i WiMAX IEEE 802.16e en xarxes òptiques d'accés basades en sistemes RoF. S'avaluen dos escenaris experimentals: en el primer, s'avalua un sistema RoF amb fibra multimode, i el segon, un sistema RoF amb fibra monomode. Els resultats permeten obtenir màrges de seguretat i abast màxim per al desplegament de sistemes RoF segons els tipus de fibra. Al mateix temps, es demostra i avalua experimentalment una nova tècnica de multiplexació per divisió en polarització de la transmissió òptica, per a millorar la coexistència en sistemes RoF.Finalment, aquesta Tesi Doctoral presenta l'estudi del modulador electro-òptic Mach-Zehnder, com a peça clau que limita el marge dinàmic de les transmissions als sistemes RoF. Al mateix temps, es proposa i avalua experimentalment una tècnica òptica de linealització del modulador Mach-Zehnder que millora el marge dinàmic del sistema RoF. V AbstractCurrent network and telecommunication systems are required to provide higher data rates in access networks to an increasing number of users. This fact is mainly due to the increase in the Internet traffic data, which is related with the higher demand of online videogames and software, the increased complexity in the content of web pages, the joint distribution of audio-visual and added-value online content, and the introduction of high-definition services and contents such as video on demand, as a result of a society increasingly more interconnected. In order to satisfy these higher data rates requirements, new techniques for the joint distribution of several wireless communication systems are proposed in this Thesis. The aim of these techniques is to facilitate the deployment of an integrated access network at the customer premises, enabling the integration of optical transmission over an optical access network and radio-frequency transmission in the same infrastructure.Two main wireless communication systems are considered in this Thesis, WiMAX (Worldwide Interoperability for Microwave Access) and UWB (Ultra-Wide Band) according to WiMedia Alliance recommendation. Comparing the bit rate and expected range, WiMAX and UWB are complementary radio technologies expected to coexist in a near future in integrated access networks. The optical access network considered in this Thesis can be regarded as a FTTH network (Fibre-to-the-Home). The wireless signals are natively transmitted over optical network, that is, without frequency upconversion and remodulation stages, over one or several optical carriers. This technology, which is known as Radio-over-Fibre (RoF), is well suited for integrated access networks.First, the requirements for...
