Abstract

UN APARATO DESCODIFICADOR EN EL QUE PARA UNA PLURALIDAD DE SIMBOLOS DISPUESTOS EN UNA FORMA DE MATRIZ, SE CODIFICAN PRIMERO Y SEGUNDO CODIGOS DE CORRECCION DE ERRORES PARA CADA PLURALIDAD DE SIMBOLOS RESPECTIVAMENTE COLOCADOS EN UNA PRIMERA DIRECCION Y EN UNA SEGUNDA DIRECCION, Y DONDE LOS DATOS DE ENTRADA SE TRANSMITEN EN LA PRIMERA DIRECCION. EL APARATO DE DESCODIFICACION INCLUYE UNA PRIMERA MEMORIA (40) PARA ESCRIBIR DATOS DE ENTRADA, UN DETECTOR DE ERRORES (36) PARA DETECTAR UN ERROR DE LOS DATOS DE ENTRADA QUE SE ESCRIBEN DENTRO DE LA PRIMERA MEMORIA (40), BASADOS EN EL PRIMER CODIGO DE CORRECCION DE ERRORES Y PARA GENERAR DATOS DE ERROR DESDE UN PRIMER CODIGO DE CORRECCION DE ERRORES. UNA SEGUNDA MEMORIA (40) ESTA DISPUESTA PARA ESCRIBIR DATOS DE ERROR DEL PRIMER CODIGO DE CORRECCION DE ERRORES Y UN CORRECTOR DE ERRORES (41) ESTA PARA EJECUTAR SECUENCIALMENTE CORRECCIONES DE ERRORES DE LOS PRIMERO Y SEGUNDO CODIGOS DE CORRECCION DE ERRORES PARA LOS DATOS DE ENTRADA QUE SE ESCRIBEN ENLA PRIMERA MEMORIA (40) UTILIZANDO LOS DATOS DE ERROR DEL PRIMER CODIGO DE CORRECCION DE ERRORES QUE SE ESCRIBEN EN LA SEGUNDA MEMORIA (40).
