Analytical models for quality of information estimation in the ultrawideband transmission

Abstract
The optimisation and design of optical transmission systems involve multiple factors and interplay between noise sources, fibre nonlinearity and dispersions. For ultrawideband systems, the total number of parameters scales with the number of channels, and the optimisation appears to be computationally challenging. To compensate for it, one can apply analytical models for the quality of transmission estimation. Those can give the statistically averaged value of the signal to noise ratio, being an effective and accurate tool instead of full-scale signal transmission simulations. In the talk, I will cover the advantage that the Gaussian noise model and its generalisation to account for interchannel Raman scattering can bring to the analysis and optimisation of the transmission systems.
