Abstract

SE DESCRIBE UN METODO PARA SINCRONIZAR LAS TRANSMISIONES DE MENSAJES EN UN SISTEMA DE TRANSMISORES DE RADIODIFUSION SIMULTANEA MULTI-REGIONAL. UN CONTROLADOR MAESTRO (116) SE ACOPLA A LOS CONTROLADORES REGIONALES (106) PARA ACTIVAR LAS TRANSMISIONES DE MENSAJES REGIONALES. EL CONTROLADOR MAESTRO (116) TAMBIEN GENERA UNA PRIMERA SEÑAL DE MEDICION DE RETARDO QUE SE ACOPLA AL PRIMER CONTROLADOR REGIONAL (106) QUE INICIA LA TRANSMISION Y, A CONTINUACION, MIDE EL RETARDO DE PROPAGACION EN LA PRIMERA REGION DE TRANSMISION. EL CONTROLADOR MAESTRO (116) GENERA, DESPUES, UNA SEGUNDA SEÑAL DE MEDICION DE RETARDO QUE SE ACOPLA AL SEGUNDO CONTROLADOR REGIONAL (106''), EN UNA REGION DE TRANSMISION ADYACENTE. EL PRIMER CONTROLADOR REGIONAL (106) TAMBIEN MIDE EL RETARDO DE PROPAGACION EN LA SEGUNDA REGION DE TRANSMISION. SE CALCULA UN RETARDO DE PROPAGACION DIFERENCIAL INTERREGIONAL A PARTIR DE LAS MEDICIONES DE LOS RETARDOS DE PROPAGACION MEDIDOS DESDE LAS PRIMERA Y SEGUNDA REGIONES DE TRANSMISION. A CONTINUACION, SE AJUSTAN LOS RETARDOS DE TRANSMISION PARA CADA TRANSMISOR REGIONAL (104) CON EL FIN DE ECUALIZAR LOS RETARDOS DE TRANSMISION DIFERENCIAL TANTO INTER COMO INTRARREGIONALES.
