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 canalbinaria (C), en donde el flujo de bit de la senal de fuente es dividido en n palabras de fuente(X1 y X2), cuyo dispositivo comprende medios de conversion (CM)adaptados para convertir dichas palabras de fuente en palabras de canal de m-bit correspondientes (y1,y2, y3). Los medios de conversion (CM) también estánadaptados para convertir laspalabra s de fuente de n-bit en palabras de canal de m-bit correspondientes, tal que la conversion para cada palabras de fuente den-bit es protectora de la paridad (tabla I)(Fig.1).Las relaciones sostienen que m>n >/- que 1, p >/- 1 y que p puedevariar. Pre ferentemente, m=n+1. Eldispositivo está adaptado para convertir la secuencia de bit de 8-bit 00010001 en la senal de fuente en la secuencia de bit de 12-bit100010010010 y paraconvertir la secuencia de bit de 8-bit 1001001 en la secuenciade bit de 12 -bit 000010010010, para limitar la longitud de ejecucion de transicion mínimarepetida en la senal de canal. También otras secuencias de 8-bit requieren una codificacion específica en secuencia de bit de 12-bit para limitar lacompresionk de la senal de canal a 7. También se revela un dispositivo de descodificacion para descodificar la senal de canal obtenida por medio del dispositivo decodificacion.
