We proposed a new method for the rate loss reduction in the hierarchical distribution matching (Hi-DM) approach for the constellation shaping. This method makes Hi-DM comparable with the enumerative sphere shaping (ESS) approach, at short block length, in terms of rate loss.

Abstract

We proposed a new method for the rate loss reduction in the hierarchical distribution matching (Hi-DM) approach for the constellation shaping. This method makes Hi-DM comparable with the enumerative sphere shaping (ESS) approach, at short block length, in terms of rate loss.
