Two-Dimensional Constellation Shaping in Fiber-Optic Communications

Two-Dimensional Constellation Shaping in Fiber-Optic Communications

Constellation shaping has been widely used in optical communication systems. We review recent advances in two-dimensional constellation shaping technologies for fiber-optic communications. The system architectures that are discussed include probabilistic shaping, geometric shaping, and hybrid probab...
