摘要

本文提出了一种基于群级标记和石墨烯形状星座的概率形(PS)无载波振幅相位(CAP)调制方案。在25公里标准单模光纤上成功进行了9.8 Gb/s的石墨烯形PS 32 ~ 24 CAP传输实验。结果表明，由于概率增益和几何整形增益，与均匀的CAP-32信号相比，我们的方案可以实现1.8 dB的接收机灵敏度提高。

Probabilistically shaped CAP based on group-level labeling and graphene-shaped constellation

This paper presents a probabilistically shaped (PS) carrier-less amplitude phase (CAP) modulation scheme enabled by group-level labeling and graphene-shaped constellation. A 9.8 Gb/s graphene-shaped PS 32-to-24 CAP transmission experiment over a 25-km standard single-mode fiber is successfully demonstrated. The results validates that our scheme can achieve a 1.8 dB receiver sensitivity improvement compared with the uniform CAP-32 signal due to the probabilistic and geometric shaping gain.
