Abstract

EN UN SISTEMA DE COMUNICACIONES QUE TIENE UNA BASE TEMPORAL PARA LA SINCRONIZACION DEL SISTEMA, SE PROPORCIONA UN METODO Y UN APARATO PARA CONTROLAR LA SENSIBILIDAD DE UN RECEPTOR (14) CARACTERIZADO POR LAS FASES DE RECEPCION (A) DE UNA SEÑAL (2, 24) QUE SE TRANSMITIO DE FORMA PREDETERMINADA POR OTRO EN RELACION CON LA BASE TEMPORAL (T0), DONDE LA RECEPCION DE LA SEÑAL SE CONFIRMA CUANDO LA AMPLITUD DE LA SEÑAL RECIBIDA SOBREPASA UN UMBRAL DETERMINADO (18, REF), (B) DETERMINANDO EL TIEMPO DE PASO DE LA SEÑAL (16) A PARTIR DE LA DIFERENCIA DE TIEMPO ENTRE EL INSTANTE DE LA RECEPCION DE LA SEÑAL RELATIVA A LA BASE TEMPORAL Y EL INSTANTE DE LA TRANSMISION DE LA SEÑAL RELATIVA A LA BASE TEMPORAL (T0), (C) CONTROLANDO LA SENSIBILIDAD DEL RECEPTOR (14) COMO UNA FUNCION DEL TIEMPO DE PASO (T0) MEDIANTE: (1) EL INCREMENTO DE LA GANANCIA DEL RECEPTOR (14) A PARTIR DE UNA SENSIBILIDAD MINIMA EN UN INSTANTE DE TRANSMISION PREDETERMINADO (T0) HASTA UNA SENSIBILIDAD MAXIMA EN UN INTERVALO MAXIMO (TIEMPOESPERADO MAXIMO DE TRANSMISION) Y (2) MANTENIENDO NOMINALMENTE LA GANANCIA DEL RECEPTOR EN EL NIVEL PREDOMINANTE EN EL MOMENTO EN QUE SE RECIBE LA SEÑAL (18).
