Abstract

EN UN PROCESO DE CODIFICACION DE VECTOR, ESPECIALMENTE PARA SEÑALES DE VOZ, LOS COEFICIENTES DE AUTOCORRELACION SON ALMACENADOS EN EL LIBRO DE CODIGOS Y ENTONCES COMBINADOS CON LA FUNCION DE AUTOCORRELACION DE LA RESPUESTA DE IMPULSOS DE UN FILTRO DE EXCITACION, QUE PRODUCE LA ENERGIA DE LA SEÑAL DE EXCITACION FILTRADA. PARA UNA REDUCCION ADICIONAL DE DATOS, SOLO SE INTRODUCEN AQUELLOS VALORES QUE TIENEN TRES COEFICIENTES DE AUTOCORRELACION O 0 EN EL LIBRO DE CODIGO. LAS PLANTILLAS DE COMBINACION, QUE PUEDEN SER FORMADAS A PARTIR DE ESTOS COEFICIENTES, TIENEN LUGAR CON IGUAL FRECUENCIA EN EL LIBRO DE CODIGO. COMO UN RESULTADO DE ESTAS MEDICIONES ES POSIBLE EFECTUAR UNA TRANSMISION RESISTENTE DE PERTURBACION ALTA DE DATOS CODIFICADOS CON COSTE REDUCIDO PARA LA MEMORIA Y EL PROCESADO.
