Abstract

La solicitud se relaciona con un método de convertir una secuencia de palabras de informacion de m-bit (1) en una senal modulada (7). Por cadapalabra de informacion recibida (1) de la secuencia hay una palabra de codigo de n-bits entregada(4 ). Las palabras de codigo entregadas (4) forman la senalmodulada (7). Cuando una de las palabras de codigo (4) se asigna a la palabra de informacion (1) esta palabra de codigo se selecciona de un juego depalabras de codigo que dependen de unestado de codificacion que se relaciona con un valor de suma digital al final de la parte de la senal modulada queresponde a la palabra de codigo entregada a ser convertida (4). Mediante lo menos uno de los valores de suma digitales esdeterminado un primero (S2, S4,S6, S8, S10, S12) o un segundo (S3, S5, S7, S9, S11, S13) estado de codificacion de un par de estados de codificacion de un primer tipo. Cuál delos dos estados de codificacion del par es determinado dependela palabra de informacion (1) que corresponde a la palabra de codigo previamente entregada(4). Los juegos (V2/V3; V4/V5; V6/V7; V8/V9; V10/V11; V12/V13) de palabras de codigo que pertenecen a los pares de estados de codificacion del primer tiponocontienen ni nguna palabra de codigo comun. En este método de codificacion el numero de células de bit consecutivas en la senal modulada que tiene el mismovalor de senal no excede de 7. Además, se requieren palabras de sincronizacion extensas,específicas par a la insercion entre los bloques de las palabras decodigo. La senal modulada (7) obtenida puede ser reconvertida a palabras de informacion (4) primero conviertiendo la secuencia de palabras de codigo en lasenal modulada (7) enuna secuencia de pa labras de informacion, asignando una palabra de codigo de informacion (1) a cada una de las palabras de codigo de
