[TuC2-1] Recent Advances in Probabilistic and Geometric Constellation Shaping

○Olga Vassilieva¹, Inwoong Kim¹, Paparao Palacharla¹ (1. Fujitsu Network Communications, Inc. (United States of America))

We discuss various techniques to optimize the performance of probabilistic and geometric constellation shaping for linear shaping gain and improved tolerance to fiber Kerr nonlinearity. These techniques are practical with reduced implementation complexity.
