Design of Non-Linear distortion compensati for long distance fibre communication

[Dr. Navneet AgrawalParticipant]

we want to generate MATLAB code for designing of non linear distortion compensatory stage so that long distance communication (> 100 km )without distortion can be observed .

The method we use in our DSP is back propagation, which is implemented in this article:

Hi Damian, unfortunately the article is available only on purchase. Any other free reference to your method? I am very interested in how the 100G nonlinear compensation works on Optisystem

I believe you should be able to access this one:

From a quick look it doesn’t look very complex. You simply add an artificial nonlinear dispersive fiber with an opposite dispersion and negative Kerr nonlinearity and also adding an artificial gain.
