Predicting Nonlinear Interference for Short-Blocklength 4D Probabilistic Shaping
Jingxin Deng, Bin Chen, Zhiwei Liang +2
We derive a heuristic nonlinear interference model for 4D probabilistic shaping considering the polarization and time correlation of the 4D symbols. We demonstrate an average SNR p…
