Abstract

LA INVENCION SE REFIERE A UN METODO PARA PROCESAR LOS PARAMETROS DE UN CODIFICADOR DE VOCES SEGUN LA CALIDAD DE LA CONEXION DE TRANSMISION. LA CALIDAD DE LA CONEXION DE TRANSMISION SE DETERMINA EN UN MIEMBRO CONTROLADOR DE LA CALIDAD (409) EN FUNCION DE UNAS CLASIFICACIONES CON ERRORES/SIN ERRORES DE LAS SECUENCIAS INDIVIDUALES RECIBIDAS DE TAL MODO QUE PARA DETERMINAR LA CALIDAD DE LA CONEXION DE TRANSMISION SE EXPLORAN LAS CLASIFICACIONES DE SECUENCIAS INDIVIDUALES REALIZADAS DURANTE VARIAS SECUENCIAS DE VOZ CONSECUTIVAS. EN FUNCION DE LA CALIDAD DE LA CONEXION DE TRANSMISION EL PROCEDIMIENTO DE SUSTITUCION DE SECUENCIAS DE VOZ CON ERRORES LLEVADO A CABO EN EL MIEMBRO DE SUSTITUCION (402) Y EL PROCESAMIENTO DE LAS SECUENCIAS DETECTADAS SIN ERRORES LLEVADAS EN EL MIEMBRO DE PROCESAMIENTO (406) DE SECUENCIAS SIN ERRORES SE CONTROLAN DE MODO QUE EL EFECTO DE LOS ERRORES EN LA TRANSMISION RELATIVOS A LA CALIDAD DE LA SEÑAL DE VOZ DECODIFICADA SIGA SIENDO INSIGNIFICANTE.
