Abstract

SISTEMA DE RADIODIFUSION DE PAQUETES DE DATOS BINARIOS. SE UTILIZA UN SISTEMA DE AGRUPAMIENTO DE DATOS. CADA GRUPO COMPRENDE UNA SECUENCIA DE BLOQUES DE DATOS. CADA BLOQUE FORMA EL CAMPO DE DATOS DE UN PAQUETE, POR LO QUE CADA PAQUETE ESTA CONSTITUIDO POR UN BLOQUE DE DATOS PRECEDIDO POR UN PREFIJO QUE CONTIENE SEÑALES DE SINCRONIZACION DE BITS Y OCTETOS, UN CODIGO DE IDENTIFICACION DE ORIGEN, UNA SEÑAL DE INDICE DE CONTINUIDAD DE PAQUETE Y UNA INFORMACION SOBRE LA ESTRUCTURA DEL PAQUETE. EL PRIMER BLOQUE DE UN GRUPO CONTIENE, ADEMAS, UN PREFACIO FORMADO POR BYTES QUE DEFINEN EL TIPO DE GRUPO, EL INDICE DE CONTINUIDAD DE GRUPO Y OTROS PARAMETROS DE INTERES, INDICANDOSE TAMBIEN EL NUMERO DE VECES QUE EL GRUPO DE DATOS SE REPETIRA, PARA PREVENCION DE ERRORES. LA REALIZACION PRACTICA SE HA CONCRETADO EN UNA PORTADORA DE 67.75 MHZ CON UN VOLUMEN DE TRANSMISION DE DATOS DE 30 KBIT/S QUE PERMITE A LA RECEPCION UN TRATAMIENTO COMPLETO POR LOGICIAL. DE APLICACION A LA RADIODIFUSION DE DATOS CON RECEPTORES MOVILES.
