Geometric Constellation Shaping for Phase-Noise Channels Using a Differentiable Blind Phase Search (Th2A.32)

Presenter: Andrej Rode, Karlsruhe Institute of Technology

We perform geometric constellation shaping with optimized bit labeling using a binary auto-encoder 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.
