Abstract

La presente tecnología se refiere a un dispositivo de procesamiento de datos y un método de procesamiento de datos, que son capaces de asegurar una excelente calidad de comunicación en la transmisión de datos utilizando un código LDPC. En la intercalación en forma de grupos, un código LDPC en el que un código de longitud N es 16200 bitios y una tasa r de codificación es de 10/15 o 12/15 es intercalado en unidades de grupos de bitio de 360 bitios. En la intercalación en forma de grupos, una secuencia de código LDPC que ha sido objeto de la intercalación en forma de grupos se restaura a una secuencia original. Por ejemplo, la presente tecnología se puede aplicar a una técnica para llevar a cabo la transmisión de datos utilizando un código LDPC.
