Abstract
UN METODO PARA EL POSICIONAMIENTO DE IMPULSOS DE EXCITACION DE CONFORMIDAD CON EL PRINCIPIO DE IMPULSOS MULTIPLES, ES DECIR, UN NUMERO DE TALES IMPULSOS SE POSICIONAN EN PUNTOS DE TIEMPO ESPECIFICOS Y CON AMPLITUD ESPECIFICA. LOS PUNTOS DE TIEMPOS Y LAS AMPLITUDES SE DETERMINAN PARTIENDO DE PARAMETROS PREDICTIVOS (AK) Y LA SEÑAL (DK) DE RESIDUOS PREDICTIVOS, MEDIANTE LA CORRELACION ENTRE UNA SEÑAL (Y) REPRESENTATIVA DE VOZ Y UNA SEÑAL (Y) SINTETIZADA COMPUESTA. ESTO PUEDE PROPORCIONAR TODAS LAS POSICIONES DE TIEMPO POSIBLES PARA LOS IMPULSOS DE EXCITACION DENTRO DE UN INTERVALO DE CUADRO DADO. DE CONFORMIDAD CON EL METODO PROPUESTO, LAS POSICIONES DE TIEMPO POSIBLE SE DIVIDEN POR UN NUMERO (NF) DE POSICIONES DE FASE Y CADA POSICION DE FASE SE DIVIDE POR UN NUMERO DE FASES (F). ESTAS FASES ESTAN LIBRES PARA EL PRIMER IMPULSO DE EXCITACION. CUANDO SE HA POSICIONADO ESTE IMPULSO, SE DENIEGA LA FASE DETERMINADA POR ESTE IMPULSO A LOS IMPULSOS SIGUIENTES DE EXCITACION, HASTA QUE SE HAN POSICIONADO TODOS LOS IMPULSOS EN UN CUADRO.
