Abstract

Se proporciona un aparato de codificación. La codificación incluye un codificador de comprobación de paridad de baja densidad (LDPC) el cual lleva a cabo la codificación de LDPC en bits de entrada en base a una matriz de comprobación de paridad para generar una contraseña de LDPC formada de 64,800 bits, en la cual la matriz de comprobación de paridad incluye una sub-matriz de palabra de información y una sub-matriz de paridad, la sub-matriz de palabra de información está formada de un grupo de una pluralidad de bloques en columna incluyendo cada una 360 columnas, y la matriz de comprobación de paridad y la sub-matriz de palabra de información están definidas por varias tablas las cuales representan posiciones del valor uno (1) presente en cada 360-ésima columna.
