Abstract

SE PRESENTA UN METODO PARA SU USO EN UNA CELULA SIMPLE DE UN SISTEMA DE COMUNICACION INALAMBRICA DEL TIPO DE LOS QUE TIENEN UNA ESTACION PRINCIPAL (10) QUE COORDINA LA COMUNICACION ENTRE UNA PLURALIDAD DE ESTACIONES REMOTAS (20) QUE ESTAN EN LA CELULA. EL METODO SE APLICA A SISTEMAS QUE UTILIZAN RADIOS DE SALTO DE FRECUENCIA LENTAS Y UN PROTOCOLO DE TIPO CSMA (CARRIER SENSE MULTIPLE ACCESS). EN ESTE CONTEXTO, EL METODO PERMITE QUE UNA ESTACION REMOTA ADQUIERA INICIALMENTE UN MODELO DE SALTO DE FRECUENCIA Y UNA BASE DE TIEMPO DE LA ESTACION PRINCIPAL Y QUE MANTENGA LA SINCRONIZACION DE FRECUENCIA DE CARA A LAS PERDIDAS DE INFORMACION DE CONTROL DEBIDAS A LOS EFECTOS DE TRANSMISION DE RADIO (POR EJ. INTERFERENCIA, RUIDO O DESVANECIMIENTO DE PROPAGACION MULTIPLE). EN LA FASE DE ADQUISICION, LA ESTACION REMOTA GENERA ACTIVAMENTE MENSAJES DE SONDA (550) QUE SON ENVIADOS A LA ESTACION PRINCIPAL DE MANERA QUE SE CONSIGA RAPIDAMENTE UNA SINCRONIZACION DE FRECUENCIA CON LA ESTACION PRINCIPAL.
