Abstract

Esta tecnología pertenece a un dispositivo de procesamiento de datos y a un método de procesamiento de datos que hacen posible asegurar una buena calidad de comunicación cuando se utiliza un código de LDPC para transmitir datos. En el intercalado por grupos, un código de LDPC que tiene una longitud de código (N) de 16,200 bits y una tasa de código (r) de 6/15, 8/15, o 10/15 se intercala en una base por grupo de bits, cada grupo de bits que tiene 360 bits de longitud. En el desintercalado por grupos, el código de LDPC desintercalado se restablece al orden original del mismo. Esta tecnología puede aplicarse, por ejemplo, para transmisión de datos o similares utilizando un código de LDPC.
