Abstract

METODO PARA EVALUAR EL PERIODO DE ESPERA EN UN DECODIFICADOR VOCAL EN TRANSMISION DISCONTINUA, Y LOS CORRESPONDIENTES DECODIFICADOR VOCAL Y TRANSMISORRECEPTOR PARA SISTEMAS DE COMUNICACION. LA INVENCION SE REFIERE A UN METODO PARA SINCRONIZACION MUTUA DEL CODIFICADOR VOCAL DEL TRANSMISOR Y DEL DECODIFICADOR VOCAL DEL RECEPTOR EN UN SISTEMA DE COMUNICACION QUE UTILIZA TRANSMISION DISCONTINUA ENTRE EL TRANSMISOR Y EL RECEPTOR. LA TRANSMISION DISCONTINUA COMPRENDE PERIODOS DE BLOQUES SECUENCIADOS TEMPORALMENTE, ALGUNOS DE CUYOS PERIODOS CONTENDRAN BLOQUES TRANSMITIDOS Y ALGUNOS PERIODOS NO CONTENDRAN TRANSMISION; POR LO CUAL EL METODO CONTIENE ETAPAS PARA GENERAR PERIODOS DE TRANSMISION DE INFORMACION (200) QUE COMPRENDEN AL MENOS UN BLOQUE Y QUE CONTIENEN INFORMACION DADA POR UN USUARIO A DICHO DISPOSITIVO TRANSMISOR, Y PERIODOS DE SILENCIO (208, 209) QUE TIENEN UNA DURACION DE AL MENOS EL PERIODO DE UN BLOQUE Y QUE CONTIENEN INFORMACION DISTINTA A LA DADA POR EL USUARIO. LA TRANSMISION DISCONTINUA COMPRENDE ADICIONALMENTE UN PERIODO (T) QUE OCURRE IRREGULARMENTE, QUE COMPRENDE ENTRE EL PERIODO DE TRANSMISION DE INFORMACION (200) Y EL PERIODO DE SILENCIO (208, 209) SIGUIENTE AL MENOS UN BLOQUE, FORMANDO ESTE PERIODO IRREGULAR UN PERIODO DE ESPERA PARA DETERMINAR LA INFORMACION RELATIVA AL PERIODO DE SILENCIO. EN EL METODO DE ACUERDO CON LA INVENCION, EL NUMERO DE PERIODOS DE BLOQUES SE CONTABILIZA EN EL RECEPTOR HASTA UN CIERTO INSTANTE; SE DETECTA EL COMIENZO DE DICHO PERIODO DE SILENCIO (208, 209); Y EN BASE A DICHO NUMERO CONTABILIZADO DE PERIODOS DE BLOQUES Y AL COMIENZO DEL PERIODO DE SILENCIO (208, 209) SE DECIDE SI EXISTE O NO UN PERIODO DE ESPERA (T) DE DICHO TIPO ENTRE DICHO PERIODO DE TRANSMISION DE INFORMACION (200) Y EL PERIODO DE SILENCIO (208) SIGUIENTE AL PERIODO DE TRANSMISION DE INFORMACION.
