Abstract
Se revela un dispositivo para codificar un flujo de bits de datos de una senal de fuente binaria (S) en un flujo de bits de datos de una senal de canal binaria (C) satisfaciendo una compresion (d, k), en donde el flujo de bits de la senal de fuente está dividido en palabras de fuente de n-bit (X1, X2), cuyo dispositivo comprende medios de conversion (CM) adaptados para convertir dichas palabras de fuente en correspondientes palabras de canal de m-bit (Y1, Y2, Y3). Los medios de conversion (CM) están también adaptados para convertir palabras de fuente de n-bits en correspondiente palabras de canal de m-bit, tal que la conversion para cada palabra de fuente de n-bit es protectora de la paridad (tabla I). Las relaciones sostienen que m > n >/= 1, p >/= 1, y p puede variar. Preferentemente, m=n+1. Además, un generador de palabras de sincronismo (9) se encuentra disponible para generar una palabra de sincronismo de q-bit también satisfaciendo dicha compresion (d, k), la dicha palabra de sincronismo comenzando con un bit '0' y finalizando con un bit '0', el dispositivo también comprendiendo medios de fusion (19) para fusionar dicha palabra de sincronismo en dicho flujo de bits de datos de la senal de canal binaria, y que q es un valor entero mayor que k. Además, se revela un dispositivo decodificador para decodificar la senal de canal obtenida por medio del dispositivo codificador.
