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 (C1), en donde el flujo de bit de la senal de fuente está dividido en palabras de fuente de n-bit (X1-X2), cuyo dispositivo comprende medios de conversion (LC) adaptados, para convertir dichas palabras de fuente en palabras de canal de m-bit correspondientes (y1, y2, y3). Cada palabra de fuente de n-bit junto con otra palabra de fuente de n-bit forman un par de palabras de fuente. Los valores de las palabras de fuente de n-bit solo difieren en el valor del bit en la qa posicion de bit q siendo una constante. Los pares de palabras de fuente están divididos en una primera parte de pares y una parte restante de pares. Los medios de conversion (LC) también están adaptados para convertir palabras de fuente de n-bit pertenecientes a la primera parte de los pares en correspondientes palabras de canal de m-bit, de tal forma que la conversion para cada una de dichas palabras de fuente de n-bit preserva la paridad y para convertir las palabras de fuente de n-bit pertenecientes a la parte restante de los pares en correspondiente palabras de canal de m-bit, de tal forma que la conversion para cada una de dichas palabras de fuente de n-bit invierte la paridad (Tabla 1) (Fig.1). Además se revela un dispositivo de decodificacion para decodificar la senal de canal obtenida por medio del dispositivo de codificacion
