Probabilistic vs. Geometric Constellation Shaping in Commercial Applications

We discuss performance and implementation aspects of geometric and probabilistic constellation shaping, which can be optimized for different applications. We show that symbol rate optimization with probabilistic shaping can further improve reach/capacity.
