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…
Geometrically-Shaped Multi-Dimensional Modulation Formats in Coherent Optical Transmission Systems
Bin Chen, Yi Lei, Gabriele Liga +4
Shaping modulation formats in multi-dimensional (MD) space is an effective approach to harvest spectral efficiency gains in both the additive white Gaussian noise (AWGN) channel an…
Analytical SNR Prediction in Long-Haul Optical Transmission using General Dual-Polarization 4D Formats
Zhiwei Liang, Bin Chen, Yi Lei +2
Nonlinear interference models for dual-polarization 4D (DP-4D) modulation have only been used so far to predict signal-signal nonlinear interference. We show that including the sig…
Capacity Bounds for Optical WDM Channels with Peak Power Constraints
Viswanathan Ramachandran, Gabriele Liga, Astrid Barreiro +1
We investigate optical WDM transmission from the standpoint of an information-theoretic interference channel. Achievable rates that outperform treating interference as noise are pr…
High-Cardinality Geometrical Constellation Shaping for the Nonlinear Fibre Channel
Eric Sillekens, Gabriele Liga, Domaniç Lavery +2
This paper presents design methods for highly efficient optimisation of geometrically shaped constellations to maximise data throughput in optical communications. It describes meth…
