Abstract
Se proporciona un transmisor. El transmisor incluye: un codificador exterior configurado para codificar bits de entrada para generar bits codificados exteriores incluyendo los bits de entrada y los bits de paridad; un rellenador de ceros configurado para constituir bits de información de Comprobación de Paridad de Baja Densidad (LDPC) incluyendo los bits codificados exteriores y los bits cero; y un codificador LDPC configurado para codificar los bits de información LDPC, en donde los bits de información LDPC son divididos en una pluralidad de grupos de bits, y en donde el rellenador de ceros rellena bits cero para al menos algunos de la pluralidad de grupos de bits, cada uno de los cuales está formado de un cierto número de bits, para constituir los bits de información LDPC con base en un patrón de acortamiento predeterminado que establece que algunos de la pluralidad de grupos de bits no están colocados en secuencia en los bits de información LDPC.
