Abstract: In this paper, a novel three-dimensional constellation diagram is proposed for optimizing the spatial coordinates of constellation points using geometric shaping (GS), which improves the constellation figure of merit (CFM) and, as a result, reduces… read more here.

Abstract: A 4-dimensional (4-D) constellation construction and encryption scheme of dimension dissecting reorganization are proposed in this paper. In this scheme, the high-dimensional constellation is constructed by gradually decomposing and superimposing the low-dimensional constellation, and the… read more here.

DOI: 10.3390/app9091889
Abstract: Constellation shaping has been widely used in optical communication systems. We review recent advances in two-dimensional constellation shaping technologies for fiber-optic communications. The system architectures that are discussed include probabilistic shaping, geometric shaping, and hybrid… read more here.
