Abstract:
(EN) Provided are an encoding method, device and apparatus. The method comprises: a transmitting device dividing a set of sequence numbers of positions of sub-channels into at least two mutually exclusive subsets according to an interleaving operation, wherein after subject to any times of the interleaving operations, each position of a sub-channel in the subset still belongs to the subset and does not belong to the other subset; the transmitting device determining a set of positions of information bits and a set of positions of frozen bits for polar codes to be encoded according to the at least two mutually exclusive subsets; and the transmitting device encoding the polar codes to be encoded according to the set of positions of information bits and the set of positions of frozen bits. The encoding method, device and apparatus provided in the present application can improve the communication performance of polar coding.
(FR) La présente invention concerne un procédé, un dispositif et un appareil de codage. Le procédé comprend les étapes suivantes : un dispositif de transmission divise un ensemble de nombres de séquences de positions de sous-canaux en au moins deux sous-ensembles mutuellement exclusifs selon une opération d'entrelacement, chaque position d'un sous-canal dans le sous-ensemble, après soumission à n'importe quel moment à des opérations d'entrelacement, appartenant toujours au sous-ensemble et n'appartenant pas à l'autre sous-ensemble ; le dispositif de transmission détermine un ensemble de positions de bits d'informations et un ensemble de positions de bits gelés pour des codes polaires à coder selon lesdits deux sous-ensembles mutuellement exclusifs ; et le dispositif de transmission code les codes polaires à coder selon l'ensemble de positions de bits d'informations et l'ensemble de positions de bits gelés. Le procédé, le dispositif et l'appareil de codage décrits dans la présente invention peuvent améliorer les performances de communication d'un codage polaire.
