Abstract

In long distance optical transmission systems, the coherent optical transceiver with wavelength division multiplexing has become a mature technology. This work investigates signal processing to further improve the data throughput of such systems. Using information theory, we have designed coded modulation schemes for the optical transmission system. We presented a modulation format for optical transmission systems which reduces the nonlinear distortion during transmission, increasing the achievable information rate. We designed machine learning techniques to increase the throughput in nonlinear fibre transmission, and carried out the first experimental demonstration of learned time-domain digital back-propagation.
