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…
Coded Modulation Schemes for Voronoi Constellations
S. Li, A. Mirani, M. Karlsson +1
Multidimensional Voronoi constellations (VCs) are shown to be more power-efficient than quadrature amplitude modulation (QAM) formats given the same uncoded bit error rate, and als…
Low-complexity Voronoi shaping for the Gaussian channel
S. Li, A. Mirani, M. Karlsson +1
Voronoi constellations (VCs) are finite sets of vectors of a coding lattice enclosed by the translated Voronoi region of a shaping lattice, which is a sublattice of the coding latt…
Improved Simulation Accuracy of the Split-Step Fourier Method
Shen Li, Magnus Karlsson, Erik Agrell
We investigate a modified split-step Fourier method (SSFM) by including low-pass filters in the linear steps. This method can simultaneously achieve a higher simulation accuracy an…
