High-Cardinality Geometrical Constellation Shaping for the Nonlinear Fibre Ch…

This paper presents design methods for highly efficient optimisation of geometrically shaped constellations to maximise data throughput in optical communications. It describes methods to analytical…

The Partially-Coherent AWGN Channel : Transceiver Strategies for Low-Complexi…

Carrier phase estimation (CPE) is one of the key requirements to perform intradyne coherent detection in optical communication systems. Residual errors in the phase estimation at the receiver, also…

Digital Back Propagation via Sub-Band Processing in Spatial Multiplexing Systems

An advanced digital backward-propagation (DBP) method using a separate-channels approach (SCA) is investigated for the compensation of inter-channel nonlinearities in spatial- and wavelength-multip…

Modelling the Delayed Nonlinear Fiber Response in Coherent Optical Communicat…

Fiber nonlinearities, that lead to nonlinear signal distortion, are normally considered to be the result of an instantaneous material response with respect to the optical field. However, in additio…

Geometric Shaping of 2-D Constellations in the Presence of Laser Phase Noise

In this article, we propose a geometric shaping (GS) strategy to design 8, 16, 32, and 64-ary modulation formats for the optical fibre channel impaired by both additive white Gaussian (AWGN) and ph…

A Modulation Format Correction Formula for the Gaussian Noise Model in the Pr…

A closed-form formula is derived, which corrects for the modulation format dependence of the Gaussian noise (GN) model in the presence of inter-channel stimulated Raman scattering (ISRS). The analy…
