Abstract:

In this thesis, first we try to propose a model based on the original C-model for fiber-link Self-Phase Modulation (SPM) noise.

Our model which is fitted on random training data sets is evaluated with respect to different performance measures such as MMSE .

Also we propose a method that enables us to track the perturbations in model parameters which are caused by the changes in channel characteristics which can happen frequently in online fiber-link transmission.

Recent tele-communication hugely relies on fiber-optic systems. Linear fiber-optic impairments can be modeled with chromatic and polarization-mode dispersion. However, nonlinear impairments such as SPM and XPM noise are much more complicated to model and compensate. In this thesis, we try to manipulate an original model which is used by Ciena Corporation called the C-model to achieve a simpler form which tracks the perturbations and performs efficiently on unknown random data stream during online transmission.
