A CCDM-based 4-Dimensional Sphere Packing Trellis-Coded Modulation Format
A novel CCDM-based 4-dimensional sphere packing trellis-coded modulation scheme for optical channel, CCDM-TCM-b4-32QAM is proposed, increases GMI by shaping the probability distribution and enhances Euclidean distances by sphere biorthogonal packing, achieving lower BER.
