Abstract[English]
A reduced number of interleaved encoded bits is obtained by encoding input bits by a polar code and interleaving a subset of the encoded bits obtained by the encoding. The polar code comprises a number of bit indices for placing bit values before encoding, including a first set of bit indices for placing values of the input bits and a second set of bit indices for placing a predetermined bit value. The first set of bit indices comprises a first subset of bit indices and a second subset of bit indices. The subset of the encoded bits corresponds to the second subset of the bit indices, and is for reducing the number of the encoded bits. An input bit value placed on both a first bit index in the first subset and a second bit index in the second subset, and the second bit index is based on the interleaving.[French]
Un nombre réduit de bits codés entrelacés est obtenu par codage de bits d'entrée par un code polaire et entrelacement d'un sous-ensemble des bits codés obtenus par le codage. Le code polaire comprend un certain nombre d'indices de bit pour placer des valeurs de bit avant le codage, comprenant un premier ensemble d'indices de bit pour placer des valeurs des bits d'entrée et un second ensemble d'indices de bit pour placer une valeur de bit prédéterminée. Le premier ensemble d'indices de bit comprend un premier sous-ensemble d'indices de bit et un second sous-ensemble d'indices de bit. Le sous-ensemble des bits codés correspond au second sous-ensemble des indices de bit et est destiné à réduire le nombre de bits codés. Une valeur de bit d'entrée est placée à la fois sur un premier indice de bit dans le premier sous-ensemble et un second indice de bit dans le second sous-ensemble, et le second indice de bit est basé sur l'entrelacement.
