Experimental Demonstration of Rate-Adaptation via Hybrid Polar-BCH Product Code for Flexible PON
Yifan Ye, Bin Chen, Xiang Li +5
The flexible-rate Polar-BCH product codes are experimentally demonstrated in a coherent passive optical network system with 16QAM for the first time. Using a new hybrid soft- and h…
A General Nonlinear Model for Arbitrary Modulation Formats in the Presence of Inter-Channel Simulated Raman Scattering
Zhiwei Liang, Bin Chen, Jiwei Xu +4
The four-dimensional nonlinear model is extended to include the inter-channel stimulated Raman scattering, enabling accurate prediction of dual-polarization four-dimensional modula…
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…
On Shaping Gain of Multidimensional Constellation in Linear and Nonlinear Optical Fiber Channel
Bin Chen, Zhiwei Liang, Yi Lei +3
Utilizing the multi-dimensional (MD) space for constellation shaping has been proven to be an effective approach for achieving shaping gains. Despite there exists a variety of MD m…
Experimental Demonstration of 16D Voronoi Constellation with Two-Level Coding over 50km Four-Core Fiber
Can Zhao, Bin Chen, Jiaqi Cai +7
A 16-dimensional Voronoi constellation concatenated with multilevel coding is experimentally demonstrated over a 50km four-core fiber transmission system. The proposed scheme reduc…
