Paper Abstract

A Probabilistic Shaping (PS) 12-QAM scheme based on Set-Partitioned (SP) Two-Polarization (TP) is proposed to improve the effectiveness and reliability of Probabilistic Shaping 12-QAM (PS-12QAM). In this scheme, the Uniform 12- QAM constellation points are divided into two set partitions, and two polarization states are used to broaden the dimension between two set partitions. Moreover, the system capacity is further approached to Shannon limit by Probabilistic Shaping. The simulations on PS-8QAM, PS-12QAM, PS-16QAM and Probabilistic Shaping Set-Partitioned Two-Polarization 12- QAM (PS-SP-TP-12QAM) have been completed. The results show that, compared with PS-12QAM, the Euclidean distance between adjacent constellation points in PS-SP-TP-12QAM scheme is significantly optimized, and the bit error rate (BER) of this scheme is greatly improved up to 0.5dB. Compared with PS-8QAM and PS-16QAM, it brings a better balance between effectiveness and reliability performance.
