Modified QPSK Partition Algorithm Based on MAP Estimation for Probabilistically-Shaped 16-QAM
Jin Hu, Zhongliang Sun, Xuekai Xu +4
Probabilistic shaping (PS) is investigated as a potential technique to approach the Shannon limit. However, it has been proved that conventional carrier phase recovery (CPR) algori…

Fixed-State Log-MAP Detection for Intensity-Modulation and Direct-Detection Optical Systems over Dispersion-Uncompensated Links
Shuangyue Liu, Ji Zhou, Haide Wang +3
In this paper, an optimized detection based on log-maximum a posteriori estimation with the fixed number of surviving states (fixed-state Log-MAP) is proposed to cooperate with equ…
