Four-dimensional signal constellations based on the checkerboard lattice D 4 offer a
packing gain over conventional QAM constellations per polarization. Due to the increased …

Forward error correction () is an essential technique required in almost all communication
systems to guarantee reliable data transmission close to the theoretical limits. In this chapter …

Probabilistic constellation shaping is studied and developed for optical phase conjugation
(OPC)-based nonlinearity compensation of Kerr nonlinearities in optical fiber links. The mid …
