Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE ELIMINACION DE SEÑALES PARASITAS EN UN ENLACE DE ESPECTRO ENSANCHADO DE SECUENCIA DIRECTA, Y COMPRENDE LAS ETAPAS SIGUIENTES: DETECCION FRECUENCIAL DE SEÑALES PARASITAS MEDIANTE COMPARACION DEL ESPECTRO DE LA SEÑAL COMPUESTA DE ENTRADA CON UN UMBRAL; FILTRADO DE LA SEÑAL COMPUESTA DE ENTRADA CON UN FILTRO DE RESPUESTA DE IMPULSOS ACABADA POR CONVOLUCION RAPIDA, EN EL QUE SE CONTROLA EL UMBRAL DE DETECCION UTILIZANDO UNA ESTIMACION DE LA DENSIDAD ESPECTRAL DE ENTRADA TRAS LA ELIMINACION DE LAS PRINCIPALES SEÑALES PARASITAS. LA INVENCION SE REFIERE ASIMISMO A UN DISPOSITIVO DE ELIMINACION DE SEÑALES PARASITAS.
