Mode Division Multiplexing using MIMO Processing

Abstract

[CASTELLÀ] Las tecnologías de multiplexación por división de modos en fibras ópticas multimodo están siendo consideradas como una de las posibles soluciones para la creciente demanda de capacidad. Los problemas derivados de este tipo de fibras se pueden superar utilizando técnicas Multiple-Input Multiple-Output (MIMO). En este proyecto final de carrera se han reportado simulaciones por ordenador con multiplexación por división de modos en fibras ópticas multimodo utilitzando procesado MIMO. La implementación del modelo matemático se basa en un sistema coherente de comunicaciones ópticas con fibras multimodo y ecualización MIMO. Se ha utilizado procesado digital de la señal para estimar la matriz de canal MIMO, invirtiendo sus efectos. El entorno de simulación creado es una herramienta de contar errores, capaz de personalizar rápidamente los experimentos mediante una interfaz gráfica fácil de utilizar, proporcionando distintos gráficos de salida. Simulaciones con validación teórica y resultados de rendimiento se han obtenido para validar el sistema, comprobar dependencias con distintos parámetros y para evaluar el rendimiento. Se da una visión general de la efectividad de las tecnologías MIMO aplicadas a sistemas de transmisión con multiplexación por división de modos.

La implementació del model matemàtic s'ha basat en un sistema coherent de comunicacions òptiques amb fibres multimode i equalització MIMO. S'ha utilitzat processat digital del senyal per estimar la matriu de canal MIMO, invertint-ne l'efecte. L'entorn de simulació creat és una eina de comptar errors, capaç de personalitzar ràpidament els experiments mitjançant una interfície gràfica fàcil d'utilitzar, proveint de diverses sortides gràfiques. Simulacions amb validació teòrica i resultats de rendiment s'han obtingut per validar el sistema, comprovar dependències amb els diversos paràmetres i per avaluar el rendiment.

[ANGLÈS] Mode division multiplexing technologies in multimode optical fibers are being considered as one of the possible solution to the ever growing user capacity demands. Problems derived from this kind of fibers can be overcome using Multiple-Input Multiple-Output (MIMO) techniques. In this thesis, computer simulations for mode division multiplexing in multimode optical fibers using MIMO processing are reported. The implementation of the mathematical model is based on a coherent optical communication system with multimode fibers and MIMO equalization. Digital Signal processing is used to estimate the MIMO channel matrix and invert its effects. The simulation environment is an error counting tool able to quickly setup customized experiments through a user-friendly graphical interface, providing numerous output displays. Theoretical validation simulations and system performance results are obtained to validate the system, check parameter dependencies and evaluate the link performance results. An overall insight of the effectiveness of MIMO technology applied to mode division multiplexed transmission systems is provided.
