Rate Loss Reduction through Look-up Table Design for Hierarchical Distribution Matcher in Probabilistic Amplitude Shaped systems
Pantea Nadimi Goki, Luca Potì · 2021
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.
