Abstract

EN UN FILTRADO DIGITAL ADAPTIVO, LAS PRIMERAS ETAPAS PARA LA ADAPTACION DE UN COEFICIENTE DE FILTRO DEPENDIENTE DE UNA MUESTRA DE DATOS RECIBIDA, Y LAS SEGUNDAS ETAPAS PARA EL FILTRADO APLICANDO UN COEFICIENTE DE FILTRO ADAPTADO A UNA MUESTRA DE DATOS RECIBIDA, SON ALTERNADAS DE MANERA QUE LOS COEFICIENTES DE FILTRO ADAPTADOS Y LAS MUESTRAS DE DATOS MODULADAS SON DETERMINADOS ALTERNATIVAMENTE. EN CONSECUENCIA, CADA COEFICIENTE DE FILTRO ADAPTADO PUEDE SER SUMINISTRADO PARA SU USO INMEDIATO EN EL FILTRADO.
