Abstract

PROCEDIMIENTO DE CANCELACION DE SEÑAL DE RUIDO EN UNA SEÑAL DE INFORMACION COMPUESTA. UNA SEÑAL DE INFORMACION COMPUESTA (E+S) COMPRENDE UNA SEÑAL DESEADA (S) Y UNA SEÑAL DE RUIDO (E), NO CORRELACIONADA. LA CANCELACION DE LA SEÑAL DE RUIDO SE CONSIGUE AL HACER PASAR A ESTA, O A UNA FUNCION DE LA MISMA (F (E)), A TRAVES DE UN CIRCUITO DE FILTRO (F), PARA FORMAR UNA ESTIMACION (E) DE ELLA QUE SE RESTA DE LA SEÑAL DE INFORMACION, CUYO RESULTADO ES UNA SEÑAL CORREGIDA MUY CERCANA A LA SEÑAL DESEADA. EL FILTRO TIENE COEFICIENTES VARIABLES (C) CUYO PROCEDIMIENTO DE AJUSTE SE BASA EN COMPARACIONES ENTRE LA SEÑAL DE RUIDO MONITORIZADA Y LA SEÑAL DE INFORMACION COMPUESTA.
