Abstract
(EN)
Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. The method includes: obtaining a maximum mother code sequence, where the maximum mother code sequence is characterized in that, if a first sequence whose code length is Z is read from the maximum mother code sequence, ordering, in the first sequence, of Z sequence numbers included in the first sequence is the same as ordering, in the maximum mother code sequence, of the Z sequence numbers, where Z=2 z , z‰¤n, and z is a positive integer; and performing polar coding by using the maximum mother code sequence.

Des modes de réalisation de la présente invention concernent un procédé, un dispositif et un équipement à utiliser dans un codage de polarisation, qui peuvent réduire la surcharge de stockage d'un système. Le procédé comprend les étapes consistant à : obtenir une séquence de code maître maximale, cette séquence de code maître maximale satisfaisant la propriété suivante : si, à la lecture d'une première séquence comprenant une longueur de code de z parmi la séquence de code maître maximale, l'ordre des nombres ordinaux de z dans cette première séquence est le même que l'ordre des nombres ordinaux de z dans la séquence de code maître maximale, dans laquelle Z = 2 z , z ≤ n, et Z est un nombre entier positif ; exécuter un codage de polarisation à l'aide de la séquence de code maître maximale.
