Abstract

En el presente documento se proponen métodos para llevar a cabo ajuste de tasa para códigos polares a través de almacenamiento en memoria intermedia circular de los bits sometidos a codificación polar. Las modalidades se dirigen a métodos de operación de un nodo de transmisión en un sistema inalámbrico que incluyen llevar a cabo codificación polar de un conjunto de bits de información de acuerdo con una secuencia polar de longitud NB para generar así NB bits codificados. El método puede incluir además intercalar los bits codificados para proporcionar de ese modo una secuencia de bits codificados intercalados, y almacenar la secuencia de bits codificados intercalados en una memoria intermedia circular de longitud NB. De acuerdo con ciertas modalidades, el método puede incluir además extraer N bits codificados para transmisión de la memoria intermedia circular. N puede ser mayor, igual o menos que NB.
