Abstract
Systems and methods of compensating for transmission impairment over an optical transmission channel are disclosed. The optical transmission channel includes an optical fiber and an optical amplifier. One such method includes: receiving an optical signal which has been distorted in the physical domain by an optical transmission channel; and solving a non-linear Schrödinger equation (NLSE) using a split-step Fourier Method (SSFM). The NLSE describes a virtual optical fiber corresponding to the optical fiber. The SSFM implements a linear operator with a wavelet-based FIR filter.
