| Main Objective: This project aims at developing and analysing models for the statistical characterisation of ICXT in MCFs, proposing techniques for mitigating those effects in MCF-based networks, and using those achievements in the development of ICXT-aware algorithms for routing, spectrum and core assignment (RSCA) in MCF-based elastic optical networks (EONs). The project focuses on the theoretical and simulation studies of the statistical characteristics of ICXT in MCF and techniques for mitigating its impact on MCF-based networks. These studies are complemented by the experimental demonstration of the main outcomes of the theoretical and simulation studies. The project takes advantage of the expertise on experimental work and system design on MCF technology of NICT (National Institute of Information and Communications Technology, from Japan) combined with the experience of IT (Optical Communications Group at Lisbon site of Instituto de Telecomunicações) on theoretical modelling and analysis of optical fibre telecommunication systems and networks. The project has three particular objectives. The first one is focused on the investigation of the modelling and statistical characterisation of ICXT of MCFs using theoretical, numerical simulation and experimental work. Particularly, the rigorous statistical and spectral characterisation of ICXT is performed, and the impact of fibre nonlinearity on ICXT statistics and spectral features is assessed. Using that characterisation, the impact of ICXT statistical features on MCF system performance is assessed. The second objective is focused on the investigation of modulation techniques for mitigation of ICXT effects in MCF-based networks, using theoretical, numerical simulation and experimental work. In particular, the ICXT mitigation achieved by adaptive techniques in orthogonal frequency division multiplexing (OFDM) modulation is assessed. Furthermore, new complex multi-core (spatial) modulation formats, that exploit the time and spectral varying characteristics and random nature of ICXT, are proposed and their performance in terms of tolerance to ICXT is compared with other multi-core modulation formats already proposed in the literature. The third objective of the project is focused on the study of the impact of ICXT on some network layer aspects of MCF-based flexgrid EONs, using theoretical and numerical simulation work. In particular, simplified equivalent models for quantification of impact of ICXT (taking into account its random nature) on the performance of MCF-based EONs are proposed, ICXT-aware RSCA algorithms taking into account the ICXT effects are proposed, and their performance is compared with the performance of other RSCA algorithms already proposed in the literature. |
