POSTDIGITAL Plus Doctoral Network

ALT Project Summary, Aim and Objectives: Growing demand for data pushes the global optical network to its limits where our conventional techniques borrowed from linear communication systems are ineffective. One of these limits comes from the intrinsic nonlinearity of the fibre channel which makes it fundamentally different from common communication channels. The nonlinearity of the fibre greatly limits what can be achieved through optical communication. Although this problem has been studied and investigated by researchers for several years, there is still a lack of a commercially viable technique to mitigate nonlinearity in modern optical systems. The current state-of-the-art is either limited to offline signal processing or real-time processing of the signal with small nonlinear distortion with limited applications. This project aims at implementing a real-time nonlinearity mitigating DSP for single-channel coherent optical communication systems.
