Abstract

UN METODO PARA LA RADIOSINCRONIZACION DE ESTACIONES BASE EN UNA RED DE TRANSMISION SIMULTANEA QUE INCLUYE UNA PLURALIDAD DE ESTACIONES BASE A SINCRONIZAR. VARIAS DE DICHAS ESTACIONES BASE TRANSMITEN SEÑALES DE SINCRONIZACION UNA DESPUES DE LA OTRA. VARIAS DE DICHAS ESTACIONES BASE RECIBEN LAS SEÑALES DE SINCRONIZACION TRANSMITIDAS MENCIONADAS CON OBJETO DE OBTENER VARIAS VALORACIONES DE LOS ERRORES DE SINCRONIZACION, SIENDO CADA UNA DE DICHAS VALORACIONES UNA VALORACION DEL ERROR DE SINCRONIZACION ENTRE UNA DE LAS ESTACIONES BASE TRANSMISORAS Y UNA DE LAS ESTACIONES BASE RECEPTORAS. PARA QUE SE CUMPLAN LOS REQUISITOS DE TRANSMISION DE TRANSMISORES SIMULTANEAS, SE AJUSTA EL TIEMPO DE LAS TRANSMISIONES POSTERIORES DE LAS ESTACIONES BASE UTILIZANDO DICHAS VALORACIONES PARA EL AJUSTE, SIENDO CADA UNA DE LAS VALORACIONES ANTEDICHAS UNA VALORACION OBTENIDA A PARTIR DE UNA SEÑAL DE SINCRONISMO QUE FUE TRANSMITIDA O RECIBIDA POR LA ESTACION BASE PARTICULAR QUE SE ESTABA AJUSTANDO.
