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…

Analytical SNR Prediction in Long-Haul Optical Transmission using General Dual-Polarization 4D Formats
Zhiwei Liang, Bin Chen, Yi Lei +2
Nonlinear interference models for dual-polarization 4D (DP-4D) modulation have only been used so far to predict signal-signal nonlinear interference. We show that including the sig…

Shaped Four-Dimensional Modulation Formats for Optical Fiber Communication Systems
Bin Chen, Gabriele Liga, Yi Lei +4
We review the design of multidimensional modulations by maximizing generalized mutual information and compare the maximum transmission reach of recently introduced 4D formats. A mo…
