Abstract

MEDIO DE DETECCION DE LOS DATOS DE NIVEL PARA SER USADOS PARA AJUSTAR PREDICCIONES DE LARGOS PERIODOS MEDIANTE UN CODIFICADOR DE PULSO DE EXCITACION CONVERSACIONAL. UN SEÑAL RESIDUAL (RDN) ES PRIMERAMENTE DERIVADA DE LA SEÑAL DE CONVERSACION (SDN) POR FILTROS DE CORTO PERIODO ENTONCES (RDN) ES PROCESADA PARA PRODUCIR UNA SEÑAL DE ERROR PREDICTIVA (EDN) PARA SER CODIFICADA COMO PULSO DE EXCITACION. LA GENERACION DE (EDN) INCLUYE LA PREDICCION DE UN RESIDUO A TRAVES DE OPERACIONES PREDICTIVAS DE LARGO PERIODO INCLUYENDO LA MEDIDA DE UN FACTOR DE NIVEL RELATIVO M, MEDIANTE UN PROCESO POR PASOS CON UN PRIMER PASO QUE PRODUCE UN VALOR DE M APROXIMADO CONTANDO LOS PASOS Y DETECCION DE LA TRANSICION DE LA SEÑAL, Y UN SEGUNDO PESO PARA AJUSTAR M A UN VALOR MAS FINO POR OPERACIONES DE AUTOCORRELACION SOBRE LOS PICOS ESPACIADOS.
