Abstract

SISTEMA CORRECTOR DE ERRORES EN EL QUE LOS DATOS DIGITALES RECIBIDOS SON SOMETIDOS A PROCESOS DE CORRECCION POR UN PRIMER Y UN SEGUNDO CODIGOS DE CORRECCION DE ERROR ALTERNATIVAMENTE. LLEVA MEMORIAS PARA ALMACENAS APUNTADORES DE ERROR DE LAPRIMERA Y LA SEGUNDA SERIE PARA VARIAS SERIES DEL PRIMER Y SEGUNDO CODIGOS DE CORRECCION DE ERROR, LEYENDOSE DICHOS APUNTADORES DE LAPRIMERA Y SEGUNDA SERIES DE ERRORES PARA DETERMINAR CUAL DE ELLAS NO TIENE ERRORES, OMITIENDOSE LOS PROCESOS DE CORRECCION DEL PRIMER Y SEGUNDO CODIGOS DE CORRECCION DE ERROR RESPECTO A LA SERIE QUE NO LO TIENE. EN CONSECUENCIA, AUMENTA EL NUMERO DE VECES QUE PUEDEN REPETIRSE LOS PROCESOS EFECTIVOS DE CORRECCION EN UN TIEMPO LIMITADO, MEJORANDO SUBSTANCIALMENTE LA CAPACIDAD DE CORRECCION.
