Abstract[English]
Polar codes for wireless communications are constructed to adapt to channel conditions. The polar code construction includes a partial code rate reduction. Input bits are encoded by a polar code to obtain a number of encoded bits, and the number of the encoded bits on bit indices in a first segment of encoded bit indices of the encoded bits is reduced. The polar code includes or provides a first set of bit indices for values of the input bits, a second set of bit indices for a predetermined bit value, and a third set of bit indices corresponding to the first segment of encoded bit indices. The second set and the third set of bit indices include a first bit index on which the predetermined bit value is placed to reduce a code rate of the first segment.[French]
Des codes polaires pour des communications sans fil sont construits pour s'adapter à des conditions de canal. La construction du code polaire comprend une réduction partielle du débit de code. Des bits d'entrée sont codés par un code polaire pour obtenir un certain nombre de bits codés, et le nombre de bits codés sur des indices de bits dans un premier segment d'indices de bits codés des bits codés est réduit. Le code polaire comprend ou fournit un premier ensemble d'indices de bits pour des valeurs des bits d'entrée, un deuxième ensemble d'indices de bits pour une valeur de bit prédéterminée et un troisième ensemble d'indices de bits correspondant au premier segment d'indices de bits codés. Le deuxième ensemble et le troisième ensemble d'indices de bits comprennent un premier indice de bit sur lequel la valeur de bit prédéterminée est placée pour réduire un débit de code du premier segment.
