Data-driven Enhancement of the Time-domain First-order Regular Perturbation Model
Astrid Barreiro, Gabriele Liga, Alex Alvarado
A normalized batch gradient descent optimizer is proposed to improve the first-order regular perturbation coefficients of the Manakov equation, often referred to as kernels. The op…
A Data-driven Optimization of First-order Regular Perturbation Coefficients for Fiber Nonlinearities
Astrid Barreiro, Gabriele Liga, Alex Alvarado
We study the performance of gradient-descent optimization to estimate the coefficients of the discrete-time first-order regular perturbation (FRP). With respect to numerically comp…
Modeling of Nonlinear Interference Power for Dual-Polarization 4D Formats
Gabriele Liga, Bin Chen, Astrid Barreiro +1
We assess the accuracy of a recently introduced nonlinear interference model for general dual-polarization 4D formats.~ Unlike previous models for polarization-multiplexed 2D forma…
Extending fibre nonlinear interference power modelling to account for general dual-polarisation 4D modulation formats
Gabriele Liga, Astrid Barreiro, Hami Rabbani +1
In optical communications, four-dimensional (4D) modulation formats encode information onto the quadrature components of two arbitrary orthogonal states of polarisation of the opti…
