On the Performance of Multidimensional Constellation Shaping for Linear and Nonlinear Optical Fiber Channel
Bin Chen, Zhiwei Liang, Shen Li +3
Multidimensional constellation shaping of up to 32 dimensions with different spectral efficiencies are compared through AWGN and fiber-optic simulations. The results show that no c…

Low-Complexity Soft-Decision Detection for Combating DFE Burst Errors in IM/DD Links
Kaiquan Wu, Gabriele Liga, Jamal Riani +1
The deployment of non-binary pulse amplitude modulation (PAM) and soft decision (SD)-forward error correction (FEC) in future intensity-modulation (IM)/direct-detection (DD) links…

Analytical Model of Nonlinear Fiber Propagation for General Dual-Polarization Four-Dimensional Modulation Format
Zhiwei Liang, Bin Chen, Yi Lei +2
Coherent dual-polarization (DP) optical transmission systems encode information on the four available degrees of freedom of an optical field: the two polarization states, each with…
