Mobile Optical Transmission Simulations - Development of a simulation framework in MATLAB

Abstract

Abstract This thesis focuses on developing a robust simulation framework in MATLAB tailored for evaluating optical communication systems in mobile fronthaul networks. Leveraging the Robochameleon library, this research aims to model and analyze systems with high-speed optical links, addressing the increasing capacity demands of modern mobile networks (5G/6G). Critical developments include integrating a precise chirp compensation model to mitigate chromatic dispersion and a printed circuit board (PCB) simulation module for assessing signal degradation in electrical domains. The modular framework supports performance metrics like Bit Error Rate (BER) and Transmitter and Dispersion Eye Closure Quaternary (TDECQ) to validate system reliability. Results illustrate the effectiveness of chirp pre-compensation and signal equalizers in improving link performance while highlighting limitations in addressing severe impairments solely through linear compensations. Furthermore, the inclusion of additional models for signal processing components could significantly enhance the framework’s accuracy and utility, facilitating broader adoption across diverse applications in next-generation optical network design and optimization.
