Abstract
La presente tecnología se refiere a un aparato de procesamiento de datos y a un método de procesamiento de datos que son capaces de proporcionar un código de LDPC con una buena proporción de errores. Un codificador de LDPC realiza codificación por un código de LDPC que tiene una longitud de código de 16200 bits y una proporción de códigos de 12/15. El código de LDPC incluye un bit de información y un bit de paridad, y una matriz H de comprobación de paridad se configura con una porción de matriz de información que corresponde al bit de información del código de LDPC y a una porción de matriz de paridad que corresponde al bit de paridad. Una porción de matriz de información de la matriz H de comprobación de paridad se representa por una tabla de valores iniciales de matriz de comprobación de paridad que representa una posición de un elemento de 1 en la porción de matriz de información a un intervalo de 360 columnas. La presente tecnología puede aplicarse a un caso de realizar una codificación de LDPC y una descodificación de LDPC.
