Optimization of Geometric Constellation Shaping for Wiener Phase Noise Channels with Varying Channel Parameters

24 Jun 2022  ·  Andrej Rode, Laurent Schmalen ·

We present a novel method to investigate the effects of varying channel parameters on geometrically shaped constellations for communication systems employing the blind phase search algorithm. We show that introduced asymmetries significantly improve performance if adapted to changing channel parameters.
