On the Performance of Multidimensional Constellation Shaping for Linear and Nonlinear Optical Fiber Channel
arXiv:2308.08968
Abstract
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 constellation is universal and the balance of required and effective SNRs should be jointly considered for the specific optical transmission scenario.
