Abstract

EN UN SISTEMA DE COMUNICACIONES QUE TIENE TRANSMISIONES QUE CONTIENEN CIERTA INFORMACION DE INTERES (147, 148) A INTERVALOS DETERMINADOS EN LA TRANSMISION, SE PROPORCIONA UN METODO PARA AISLAR Y PROCESAR LA INFORMACION DE INTERES. EL METODO SE CARACTERIZA POR LA PERCEPCION DEL COMIENZO DE UNA TRANSMISION (141) Y EL AISLAMIENTO PARA EL PROCESAMIENTO COMO INFORMACION DE INTERES, LA INFORMACION RECIBIDA EN MOMENTOS DETERMINADOS SE RETIRA A TIEMPO (145) DEL COMIENZO PERCIBIDO DE LA TRANSMISION (141). DE ESTE MODO, LA INFORMACION DE INTERES SE AISLA PRINCIPALMENTE EN BASE AL TIEMPO TRANSCURRIDO. EL METODO PARA AISLAR Y PROCESAR ESTA INFORMACION DE INTERES SE CARACTERIZA ADEMAS POR LA PERCEPCION (249) DEL COMIENZO DE UNA TRANSMISION A PARTIR DE LA POTENCIA DE SEÑAL RECIBIDA DE LA TRANSMISION QUE EXCEDE DE CIERTO UMBRAL DETERMINADO (259); MEDIANTE EL AISLAMIENTO AGC DE LA TRANSMISION (233) Y LA ATENUACION DE LA TRANSMISION AGC DESDE UN NIVEL MAXIMO A UN NIVEL DESEADO ANTES DEL MOMENTO EN QUESE ESPERA QUE LLEGUE LA TRANSMISION; MEDIANTE EL AISLAMIENTO PARA SU PROCESAMIENTO COMO INFORMACION DE INTERES, LA INFORMACION RECIBIDA EN INSTANTES DETERMINADOS SE RETIRA A TIEMPO DEL INICIO PERCIBIDO DE LA TRANSMISION, TEMPORIZANDO (263) EL INTERVALO ESPERADO ENTRE EL INSTANTE EN QUE SE PERCIBE EL INICIO DE LA TRANSMISION Y EL INSTANTE PREDETERMINADO EN QUE LA INFORMACION DE INTERES DEBE LLEGAR (POR LO CUAL, LA INFORMACION DE INTERES SE AISLA PRINCIPALMENTE EN BASE AL TIEMPO TRANSCURRIDO); ETIQUETANDO LA INFORMACION AISLADA (247) EN ESE INSTANTE PARA EL PROCESAMIENTO; Y COMENZANDO EL PROCESAMIENTO (275) CON LA INFORMACION QUE PRECEDE JUSTO A LA INFORMACION AISLADA (MEDIANTE LO CUAL SE AUMENTA LA FIABILIDAD DE LA DETECCION DE LA INFORMACION POR MEDIO DE UNO A VARIOS BITS).
