Lattice-based geometric shaping
Ali Mirani, Erik Agrell, Magnus Karlsson · 2020
Geometrically shaped multidimensional constellations with more than 1028points are simulated using fast and low-complexity algorithms without any look-up tables to store the constellation points. At the same symbol error rate, more than 78% and 114% reach improvement are demonstrated compared with 4- and 16-QAM, respectively.
