Abstract
(EN)
The present invention relates to the technical field of probabilistic constellation shaping, in particular in combination with polar coding. The invention accordingly proposes a device for probabilistic constellation shaping. In particular, the device is configured to: receive a first bit sequence including at least two sub-sequences; separately interleave each of the sub-sequences, form a second bit sequence including the at least two sub-sequences after interleaving; and map the second bit sequence to a plurality of symbols and thereby map at least one of the sub-sequences to one or more pre-defined bit-levels.

La présente invention concerne le domaine technique de la mise en forme probabiliste de constellation, en particulier en combinaison avec un codage polaire. L'invention propose ainsi un dispositif de mise en forme probabiliste de constellation. En particulier, le dispositif est configuré pour : recevoir une première séquence de bits comprenant au moins deux sous-séquences; entrelacer séparément chacune des sous-séquences, former une seconde séquence de bits comprenant les au moins deux sous-séquences après entrelacement; et mapper la seconde séquence de bits sur une pluralité de symboles et ainsi mapper au moins une des sous-séquences à un ou plusieurs niveaux de bits prédéfinis.
