Abstract

UNA CORRIENTE DE DATOS DISPONE DE BASTIDORES DE LONGITUD VARIABLE O FIJA, AUNQUE DETERMINADA E INCLUYE UN COLECTOR DE LONGITUD FIJA EN UNA POSICION PREDETERMINADA EN EL BASTIDOR, DICHO COLECTOR DISPONE DE UNA ESTRUCTURA DE CODIGO LINEAL SISTEMATICO QUE INCLUYE DIGITOS DE INFORMACION Y DIGITOS DE VERIFICACION. LOS DIGITOS DE VERIFICACION SE UTILIZAN PARA LA DETECCION DE SINCRONIZACION DE MARCO, COMO ASI TAMBIEN PARA DETECTAR Y CORREGIR ERRORES, UTILIZANDO, POR EJEMPLO, UN DECODIFICADOR CRC (CONTROL DE REDUNDANCIA CICLICA) MODIFICADO.
