Resumo:
Digital Back-Propagation (DBP) is a promising technique to compensate nonlinear
distortions in optical communications systems, focusing mainly on the Nonlinear
Schr¨odinger Equation and the Split-Step Fourier Method.
This report describes, after a theoretical review, a numerical simulation of
this technique, using MATLABR
, applied to a chirped Gaussian pulse emitted by a
laser source that propagates through the optical fiber, with the intent of analyzing
its effectiveness and limitations.
Until recently, compensation of linear and nonlinear impairments were processed
separately. DBP comes as a versatile and universal technique to jointly
compensate both kinds of distortions.
