Probabilistic constellation shaping has been used in long-haul optically amplified coherent
systems for its capability to approach the Shannon limit and realize fine rate granularity. The …

Probabilistic shaping of quadrature amplitude modulation (QAM) is used to enhance the
sensitivity of an optical communication system. Sensitivity gains of 0.43 and 0.8 dB are …

This work proposes a probabilistic shaping scheme for optical WDM systems, where
nonlinear interference noise depends on the input optical signal power distribution. With …

Probabilistic amplitude shaping (PAS) is a practical means to achieve a shaping gain in
