Abstract

We review the recent advances in the design of probabilistic shaping algorithms. We investigate the implementation complexity of these algorithms in terms of required storage and computational power. We show that (1) the optimum performance can be achieved via different algorithms creating a trade-off between storage and computational complexities, and (2) a significant reduction in complexity can be achieved via the recently-proposed shift-based band-trellis enumerative sphere shaping if a slight degradation in performance is tolerated.
