Abstract

La presente invención se relaciona con un dispositivo de procesamiento de datos y un método de procesamiento de datos capaz de mejorar la resistencia a errores de datos. En un caso donde los códigos de LDPC que tienen una longitud de código de 4,320 bits se mapean en dieciséis puntos de señales, un desmultiplexor realiza reemplazo de asignación b0 a y0, b1 a b4, b2 a y1, b3 a y6, b4 a y2, b5 a y5, b6 a y3, y b7 a y7 para códigos de LDPC con una proporción codificada de 1/2 , y asignación de b0 a y0, b1 a b4, b2 a y5, b3 a y2, b4 a y1, b5 a y6, b6 a y3, y b7 a y7 para códigos de LDPC con proporciones codificadas de 7/12, 3/3 y 3/4, donde(#i+1)-ésimos bits de los bits más significativos de los bits de signo de 4x2bits y de los bits de símbolo de 4x2bits de dos símbolos sucesivos representados por bits de b#i e y#i, respectivamente. La presente invención puede aplicarse, por ejemplo a un sistema de transmisión que transmite códigos de LDPC.
