Abstract

LA MEMORIA CORROMPIDA SE DETECTA DURANTE LA SECUENCIA DE COMUNICACION GENERANDO UNA SUMA DE COMPROBACION DEL CODIGO DE AUTENTIFICACION EN EL INICIO DE LA SECUENCIA DE COMUNICACION Y COMPARANDOLA CON UNA SUMA DE COMPROBACION PREVIAMENTE ALMACENADA. SI LAS SUMAS DE COMPROBACION NO CONCUERDAN SE INICIA UNA SECUENCIA DE RESINCRONIZACION EN LA CUAL SE GENERAN NUMEROS ALEATORIOS POR EL TRANSMISOR Y SE EMITEN HACIA EL RECEPTOR PARA SU USO SUBSECUENTE COMO VARIABLES DE REGISTRO DE DESPLAZAMIENTO DE REALIMENTACION LINEAL O DE CODIGO RODANTE.
