Abstract
La presente tecnología se refiere a un dispositivo de proceso de datos y a un método de proceso de datos que hace posible asegurar buena calidad de comunicación en una transmisión de datos que usa códigos de LDPC. En la intercalación en forma de grupos, un código de LDPC cuya longitud de código es 16200 bits y la tasa de códigos es de 10/15, 11/15, 12/15, o 13/15 se intercala en una unidad de grupo de 360 bits. En la desintercalación en forma de grupos, una secuencia del código de LDPC después de la intercalación en forma de grupos obtenida de los datos transmitidos de un dispositivo de transmisión a la secuencia original. La tecnología presente puede aplicarse, por ejemplo, para transmisión de datos o similares que usa los códigos de LDPC.
