Geometric Constellation Shaping for Phase-noise Channels Using a Differentiable Blind Phase Search

6 Dec 2021 · Andrej Rode, Benedikt Geiger, Laurent Schmalen ·

We perform geometric constellation shaping with optimized bit labeling using a binary autoencoder including a differential blind phase search (BPS). Our approach enables full end-to-end training of optical coherent transceivers taking into account the digital signal processing.
