Abstract

LA INVENCION CONSISTE EN UNA NUEVA CLASE DE SISTEMA DE CODIFICACION ACUSTICA PARAMETRICA, EN EL QUE LA PARAMETRIZACION, DE CONFORMIDAD CON UN MODELO DE PRODUCCION ACUSTICO, SE LLEVA A CABO NO SOLAMENTE SOBRE LA SEÑAL ACUSTICA A CODIFICAR SINO TAMBIEN EN LA DECODIFICADA, ESTO ES, SEÑAL ACUSTICA SINTETIZADA. SE COMPARA UNA REPRESENTACION PARAMETRICA (207) DE LA SEÑAL SINTETIZADA CON UNA SEÑAL PARAMETRICA (203) DE LA SEÑAL ORIGINAL ACUSTICA, Y SE CONTROLAN LAS FUNCIONES DE CODIFICACION CONFORME A SU DIFERENCIA. AL PRINCIPIO, SE REALIZA LA PARAMETRIZACION (205) CONFORME AL MODELO DE PRODUCCION ACUSTICA USADO EN LA CODIFICACION SOBRE LA SEÑAL ACUSTICA DECODIFICADA. A CONTINUACION, SE COMPARAN (204) LOS VALORES PARAMETRICOS FORMADOS DE LAS SEÑALES ACUSTICAS SINTETIZADAS, CON LOS VALORES (203) PARAMETRICOS CALCULADOS EN EL CODIFICADOR, DE LA SEÑAL ACUSTICA A CODIFICAR. SE PUEDE USAR, AL REALIZAR LA COMPARACION, UNA MEDICION DE DISTANCIAS CONOCIDA. SE CONTROLAN LAS FUNCIONES DE CODIFICACION MEDIANTE UN BLOQUE (202) DE CONFIGURACION, EN TAL FORMA QUE LA DIFERENCIA INDICADA POR LA MEDIDA DE DISTANCIAS SE HACE TAN PEQUEÑA COMO SEA POSIBLE.
