Abstract

LA PRESENTE INVENCION PRESENTA UN METODO DE CODIFICACION DE DATOS DE COEFICIENTE DE PREDICCION LINEAL. LA PRESENTE INVENCION TRANSFORMA LOS DATOS DE COEFICIENTE DE PREDICCION LINEAL EN DATOS COSENO DE ESPECTRO LINEAL (103). EL DATO COSENO DE ESPECTRO LINEAL SE UTILIZA PARA GENERAR DOS VECTORES DEFINIDOS POR RECURRENCIA (104). ESTOS SE UTILIZAN PARA CALCULAR UN CONJUNTO DE VALORES DE AUTOCORRELACION DE SENSIBILIDAD (106A-106N) Y UN CONJUNTO DE VALORES DE CORRELACION CRUZADA DE SENSIBILIDAD (107A107N). LOS VALORES COSENO DE ESPECTRO LINEAL SE UTILIZAN PARA CALCULAR UN CONJUNTO DE VALORES DE RAIZ CUADRADA DE ESPECTRO LINEAL.
