Abstract:
(EN) The present application relates to the technical field of communications. Disclosed are an interleaving method, deinterleaving method and device for increasing randomness of Polar code interleaving. The method comprises: acquiring a bit sequence for interleaving, the bit sequence for interleaving comprising L sub-sequences, the L sub-sequences comprising S sub-sequence groups, the S sub-sequence groups at least comprising a first sub-sequence group and a second sub-sequence group, the first sub-sequence group at least comprising 2 sub-sequences, the second sub-sequence group at least comprising 1 sub-sequence, where L is a positive integer greater than 1; and interleaving the sub-sequences in the first sub-sequence group using a first interleaving method, and interleaving the sub-sequences in the second sub-sequence group using a second interleaving method or not interleaving the sub-sequences in the second sub-sequence group.
(FR) La présente invention se rapporte au domaine technique des communications. L'invention concerne un procédé d'entrelacement, un procédé et un dispositif de désentrelacement destinés à accroître le caractère aléatoire de l'entrelacement d'un code polaire. Le procédé comporte les étapes consistant à: acquérir une suite de bits pour l'entrelacement, la suite de bits pour l'entrelacement comportant L sous-suites, les L sous-suites comportant S groupes de sous-suites, les S groupes de sous-suites comportant au moins un premier groupe de sous-suites et un second groupe de sous-suites, le premier groupe de sous-suites comportant au moins 2 sous-suites, le second groupe de sous-suites comportant au moins 1 sous-suite, où L est un entier positif supérieur à 1; et entrelacer les sous-suites du premier groupe de sous-suites à l'aide d'un premier procédé d'entrelacement, et entrelacer les sous-suites du second groupe de sous-suites à l'aide d'un second procédé d'entrelacement ou ne pas entrelacer les sous-suites du second groupe de sous-suites.
