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…
Order within disorder: spectral key generation and distribution in random lasers
Zhijia Hu, Shilong He, Lianghao Qi +15
In secure communication, highly random entropy sources are essential for information security. Random lasers (RLs), which arise from multiple scattering in disordered structures, a…
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…
