A Simplified Method for Optimising Geometrically Shaped Constellations of Higher Dimensionality
arXiv:2307.05179
Abstract
We introduce a simplified method for calculating the loss function for use in geometric shaping, allowing for the optimisation of high dimensional constellations. We design constellations up to 12D with 4096 points, with gains up to 0.31 dB compared to the state-of-the-art.
