Abstract
La presente tecnología se refiere a un dispositivo de procesamiento de datos y un método de procesamiento de datos, los cuales son capaces de asegurar la excelente calidad de comunicación en la transmisión de datos utilizando un código LDPC. En la intercalación en forma de grupos, en el cual una longitud N de código es de 16200 bitios y una velocidad r de codificación es 12/15, 6/15, o 8/15 que se intercala en unidades de grupos de bitios de 360 bitios. En la des-intercalación en forma de grupos, una secuencia del código LDPC que se ha sometido a la intercalación en forma de grupos se restauró a una secuencia original. Por ejemplo, la presente tecnología se puede aplicar a una técnica de llevar a cabo la transmisión de datos utilizando un código LDPC.
