Mapping Strategies for Short-Length Probabilistic Shaping

Mapping techniques for probabilistic amplitude shaping are reviewed. We focus on energy considerations, classification of methods and systems, and implementation aspects. A numerical study of required block lengths is carried out for two short-blocklength applications, namely achieving half of the maximum shaping gains and enabling rate adaptivity.
