Multi-dimensional Joint Probabilistic and Geometric Shaping Strategies for Nonlinear Fiber Communications

Published 5 Nov 2019 in math.OC and eess.SP | (1911.01908v1)

Abstract: Constellation shaping is reviewed and revised for a WDM unrepeated system with high spectral efficiency. It is shown that for a constellation size-constrained system, previous optimization techniques can be highly sub-optimal, and a superior optimization algorithm is proposed.
