Abstract

Un aparato receptor incluye: un primer decodificador configurado para decodificar una señal transmitida a través de una primera capa a partir de una señal de multiplexación por división en capas (LDM) utilizando una matriz de comprobación de paridad para generar bits de palabra de información de comprobación de paridad de baja densidad (LDPC) y bits de paridad; un codificador configurado para codificar los bits de palabra de información LDPC, generados al decodificar la señal transmitida a través de la primera capa, utilizando la matriz de comprobación de paridad para generar bits de paridad correspondientes solamente a columnas predeterminadas en la matriz de comprobación de paridad; y un segundo decodificador configurado para decodificar una señal obtenida al eliminar, de la señal LDM, una señal correspondiente a los bits de palabra de información LDPC generados al decodificar la señal transmitida a través de la primera capa, los bits de paridad generados por el codificador, y los bits de paridad generados por el primer decodificador a excepción de los bits de paridad generados por el codificador, para generar de ese modo bits de palabra de información transmitidos a través de una segunda capa.
