Coded Modulation based on 56APSK with Hybrid Shaping for High Spectral Efficiency Transmission

We discuss a multi-dimensional coded modulation format with hybrid constellation shaping (4D-PS-9/12-56APSK). The proposed format is designed to approach Shannon limit and to improve the performance of nonlinearity compensation over conventional and probabilistically shaped 2D formats.
