Abstract

LA INVENCION SE REFIERE A UN METODO PARA DISMINUIR EL PORCENTAJE DE ERROR DE BLOQUE DE LA INFORMACION A TRANSMITIR EN FORMA DE BLOQUES DE DATOS EN UN SISTEMA DE TRANSMISION DE DATOS, EN EL CUAL LA INFORMACION A TRANSMITIR ESTA DIVIDIDA EN BLOQUES DE DATOS (102,202). EL BLOQUE DE DATOS (102, 202) ES SUPLEMENTADO CON DATOS DE DETECCION DE ERROR GENERADOS UTILIZANDO PARTE DE LA INFORMACION A TRANSFERIR. AL MENOS PARTE DE LA INFORMACION A UTILIZAR PARA GENERAR LOS DATOS DE CORRECCION DE ERROR ES PROTEGIDA POR CODIFICACION DE CORRECCION DE ERROR (107, 206), OBTENIENDOSE UN BLOQUE DE DATOS DE CORRECCION DE ERROR EN EL QUE, AL MENOS, DIFERENTES PARTES DE LA INFORMACION PROTEGIDA TIENEN DIFERENTES PORCENTAJES DE ERROR (BER). LOS BLOQUES DE DATOS CODIFICADOS DE CORRECCION DE ERROR (111,112) SON TRANSFERIDOS DESDE EL TRANSMISOR AL RECEPTOR POR EL CANAL DE TRANSMISION DE DATOS. LOS PORCENTAJES DE ERROR DE, AL MENOS, UNA PARTE DE LA INFORMACION PROTEGIDA SON NIVELADOS CONFORMANDO EN LA ETAPA DE TRANSMISION AL MENOS UNA PARTE DE ESTA INFORMACION (207) QUE ESTA PROTEGIDA POR LA CODIFICACION DE ERROR Y QUE ES UTILIZADA PARA GENERAR LOS DATOS DE CORRECCION DE ERROR.
