dc.description.abstractLa creciente demanda de servicios inalámbricos que prometen acceso en cualquier momento y lugar ha generado un agotamiento del espectro electromagnético, lo que plantea la necesidad de mejorar los sistemas de comunicación existentes. En este trabajo de tesis se propone un sistema de radio sobre fibra basado en el uso de un oscilador optoelectrónico como una posible solución para mejorar el uso del espectro en altas frecuencias y garantizar características de transmisión óptimas. Se presenta la simulación de un prototipo de transmisión punto a punto que utiliza un oscilador optoelectrónico de modulación externa aplicado a un sistema de radio sobre fibra, analizando los resultados del enlace de bajada. Con esta finalidad, se caracterizó un sistema de radio sobre fibra con la ayuda del radio definido por software en la banda de frecuencia 5,8 GHz. Luego, se desarrolló un oscilador optoelectrónico diseñado para esta misma banda de frecuencia. Finalmente se llevó a cabo una simulación donde se integra el sistema, en donde se contrastaron los resultados obtenidos con las características sugeridas por diferentes estándares y protocolos, para luego evaluar las figuras de mérito del sistema. Los resultados conseguidos permitieron observar la directa relación entre las figuras de mérito trabajadas y su comportamiento bajo diferentes condiciones y esquemas de modulación, para el sistema de radio sobre fibra. En cuanto al oscilador optoelectrónico se pudieron analizar las condiciones de mejora para el ruido de fase y la estabilidad del oscilador. Finalmente se realiza la integración del sistema de radio sobre fibra con el oscilador optoelectrónico, mediante una simulación, verificando las diferentes figuras de mérito y analizando su rendimiento en distintos escenarios.

dc.description.abstractThe increasing demand for wireless services promising access anytime and anywhere has led to a depletion of the electromagnetic spectrum, prompting the need for improving existing communication systems. In this thesis work, a Radio-over-Fiber (ROF) system is proposed based on the utilization of an optoelectronic oscillator as a potential solution to enhance spectrum utilization at high frequencies and ensure optimal transmission characteristics. A simulation of a point-to-point transmission prototype is presented, employing an externally modulated optoelectronic oscillator applied to a ROF system, and analyzing the results of the downlink link. To achieve this objective, a ROF system was characterized using software-defined radio in the 5,8 GHz frequency band. Subsequently, an optoelectronic oscillator designed for this same frequency band was developed. Finally, a simulation was conducted to integrate the system, contrasting the obtained results with characteristics suggested by different standards and protocols, and then evaluating the system's performance metrics. The achieved results allowed observing a direct relationship between the performance metrics studied and their behavior under different conditions and modulation schemes for the ROF system. Regarding the optoelectronic oscillator, improvements in phase noise and stability conditions were analyzed. Finally, the integration of the radio over fiber system with the optoelectronic oscillator is carried out through a simulation, verifying the different figures of merit, and analyzing its performance in various scenarios.eng
