Abstract

PROCEDIMIENTO PARA PREPARAR SEÑALES DE APOYO (G'' SUB,I}) PARA APOYAR UN DEMODULADOR (DM) MEDIANTE UN DECODIFICADOR (DD), CON LA TRANSMISION CODIFICADA DE BITS DE DATOS (D SUB,K}) POR MEDIO DE UN ALFABETO SIMBOLICO DE CANALES CON M ETAPAS. PARA ACORTAR LOS TIEMPOS DE FUNCIONAMIENTO DE LAS SEÑALES DE APOYO (G'' SUB,I}) REALIMENTADAS DESDE EL DECODIFICADOR DE DATOS (DD) AL DEMODULADOR (DM), ESTAS MUESTRAN UNA INFORMACION LIMITADA, QUE PUEDE LIMITARSE POR EJEMPLO A UNA INFORMACION SOBRE A CUAL DE ENTRE VARIOS GRUPOS DE SIMBOLOS DE CANAL (C'' SUB,I}) PERTENECEN POR ESTIMACION LOS SIMBOLOS DE CANAL (C'' SUB,I}) TRANSFERIDOS O EN QUE GRUPO DE ESTADOS SE ENCUENTRA LA RUTA A TRAVES DEL DIAGRAMA DE TREILLIS PRECISAMENTE POR ESTIMACION.
