Title (EN) DISTRIBUTED CRC POLAR CODES
(FR) CODES POLAIRES CRC DISTRIBUÉS
Abstract:
(EN) A method comprising: determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.
(FR) La présente invention concerne un procédé qui consiste : à déterminer une séquence de générateur de contrôle de redondance cyclique (CRC) définissant une correspondance biunivoque entre une séquence de valeurs d'informations de contrôle et des valeurs de séquence de contrôle de redondance cyclique (CRC) ; et à déterminer une séquence combinée, la séquence combinée étant formée par la distribution de la séquence de valeur de contrôle de redondance cyclique (CRC) dans la séquence de valeurs d'informations de contrôle, la distribution de la séquence de valeurs de contrôle de redondance cyclique (CRC) dans la séquence de valeurs d'informations de contrôle étant basée sur une partie sélectionnée de la séquence de générateur de contrôle de redondance cyclique (CRC).
