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.A receiving apparatus includes: a first decoder configured to decode a signal transmitted through a first layer from a layered division multiplexing (LDM) signal using a parity check matrix to generate word bits of check information low density parity (LDPC) and parity bits; an encoder configured to encode the LDPC information word bits, generated by decoding the signal transmitted through the first layer, using the parity check matrix to generate parity bits corresponding only to predetermined columns in the parity check matrix ; and a second decoder configured to decode a signal obtained by removing, from the LDM signal, a signal corresponding to the LDPC information word bits generated by decoding the signal transmitted through the first layer, the parity bits generated by the encoder , and the parity bits generated by the first decoder with the exception of the parity bits generated by the encoder, to thereby generate information word bits transmitted through a second layer.
