Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y UNA DISPOSICION PARA LA ACTIVACION DE DOS ANTENAS DE UN EQUIPO DE RECEPCION. LA DISPOSICION MUESTRA UN PROCESADOR (DECT-C) CENTRAL, ASI COMO UN EQUIPO (RSSI-C) PARA LA MEDICION DE INTENSIDAD DE CAMPO A TRAVES DE LAS SEÑALES RECIBIDAS POR LAS DOS ANTENAS (A1,A2) Y UN GENERADOR (TH-G) DE VALOR UMBRAL. EL PROCESADOR (DFT-C) CENTRAL REALIZA UN PROCESO DE ETAPAS DISEÑADO DE TAL MODO, QUE DURANTE INTERVALOS DE TIEMPO SUCESIVOS SE MIDE LA INTENSIDAD DE CAMPO DE LAS SEÑALES RECIBIDAS DURANTE EL INTERVALO DE TIEMPO CORRESPONDIENTE A TRAVES DE LAS ANTENAS (A1,A2) ACTIVADAS DURANTE ESE INTERVALO DE TIEMPO. DEPENDIENDO DE LA INTENSIDAD DE CAMPO, MEDIDO DURANTE LOS INDICADOS INTERVALOS DE TIEMPO SUCESIVOS, UNA U OTRA ANTENA (A1,A2) ES ACTIVADA PARA LA RECEPCION DE SEÑALES EN EL INTERVALO DE TIEMPO QUE SIGUE AL INTERVALO DE TIEMPO DURANTE EL CUAL SE REALIZA LA MEDIDA.
