N1 - Funding Information: Fig. 1 The OFDM signal (a), the corresponding discrete spectrum (b). The use of an adaptive step size made it possible to reduce by approximately 3 times the running time of the algorithm in comparison with the PJT with a constant step and increased its accuracy in regions where discrete eigenvalues are close to each other. Moreover, PJT is one order of magnitude faster than the contour integral method and FNFT for considered computational grid sizes.

N2 - The inverse scattering transform (IST) allows to integrate the nonlinear Schrödinger equation (NLSE) equation analytically [1] and consists of three main steps: the first step is solving the direct Zakharov-Shabat problem (ZSP) to determine scattering data, the second is an evolution of the scattering data, and the third step is solving the inverse scattering problem to restore a solution from the scattering data. This method, also known as the nonlinear Fourier transform (NFT), has recently attracted much attention in areas where NLSE is used to describe various types of optical signals such as lasers and telecommunications.
