Abstract

EL CONTROL DEL NIVEL DE POTENCIA TRANSMISORA AUTOMATICO EN ENLACES RADIO MULTILINEA QUE USAN UNA MODULACION QAM MULTINIVEL ESTA BASICAMENTE COMPRENDIDO DE: - MEDIOS PARA DERIVAR UNA SEÑAL UMBRAL POR CADA CANAL RF EN CADA RECEPTOR; - MEDIOS PARA MULTIPLEXAR TODAS LAS SEÑALES UMBRAL DE LOS RECEPTORES INDIVIDUALES; - MEDIOS PARA INSERTAR UNA SEÑAL APROPIADA EN EL DICHO MULTIPLEXADOR COMO SEA NECESARIO PARA IDENTIFICAR LA ESTACION QUE NOS LLEGA; - MEDIOS PARA ADEMAS MULTIPLEXAR LA DICHA SEÑAL MULTIPLEXADA CON OTRAS SEÑALES DE SERVICIO; - MEDIOS PARA INSERTAR ESTA SEÑAL MULTIPLEXADA DOBLE EN LA ESTRUCTURA DE LA SEÑAL DE INFORMACION PRINCIPAL ENVIADA EN LA OTRA DIRECCION DE TRANSMISION; - MEDIOS PARA RECIBIR Y DESMULTIPLEXAR LA SEÑAL RECIBIDA DOS VECES; - MEDIOS PARA PROCESAR LA DICHA SEÑAL DESMULTIPLEXADA PARA DERIVAR, EN UNA MANO, UNA SEÑAL DE CONTROL DEL NIVEL DE POTENCIA TRANSMISORA, PROTEGIDA DE POSIBLES FALTAS O MALFUNCIONES DEL CANAL DIGITAL TRANSMISOR PRINCIPAL Y, EN LA OTRA MANO, LA SEÑAL DE IDENTIFICACION DE LA ESTACION; MEDIOS PARA APLICAR LA DICHA SEÑAL DE CONTROL AL CIRCUITO DE PREDISTORSION EN EL AMPLIFICADOR DE POTENCIA TRANSMISORA.
