Abstract

LA INVENCION SE REFIERE A UN METODO PARA CODIFICAR UN VECTOR DE SEÑAL DE DISCURSO MUESTREADO (S(N)) EN UN METODO DE CODIFICACION DE ANALISIS POR SINTESIS FORMANDO UN VECTOR DE EXCITACION OPTIMO QUE COMPRENDE UNA COMBINACION LINEAL DE UN VECTOR DE CODIGO A PARTIR DE UN CATALOGO DE CODIGO FIJO (12) Y UN VECTOR DE PREDICCION A LARGO PLAZO. UNA PRIMERA ESTIMACION DEL VECTOR DE PREDICCION A LARGO PLAZO SE FORMA EN UN ANALISIS DE BUCLE ABIERTO (22,24,30,32,34,36). UNA SEGUNDA ESTIMACION DEL VECTOR DE PREDICCION A LARGO PLAZO SE FORMA EN UN ANALISIS DE BUCLE CERRADO (GL, 14, 16, 20, 24, 28, 34, 36,). FINALMENTE, CADA UNA DE LA PRIMERA Y SEGUNDA ESTIMACION SE COMBINAN EN UNA BUSQUEDA EXHAUSTIVA (GJ, GL, 14, 16, 20, 22, 24, 28, 36) CON CADA VECTOR DE CODIGO DEL CATALOGO DE CODIGO FIJO (12) PARA FORMAR ESE VECTOR DE EXCITACION QUE OFRECE LA MEJOR CODIFICACION DEL VECTOR DE SEÑAL DE DISCURSO (S(N)).
