Abstract

Un método para ajustar la potencia de la senal de transmision en una disposicion de comunicaciones satelitales, particularmente para controlar unparámetro asociado con una primera senal (410) transmitida desde una primera estacion (120) au na segunda estacion (124) en una disposicion decomunicacion (100) que monitorea una segunda senal (420) transmitida desde la segunda estacion a la primea estacion (120) para determinar un estado depropagacion asociado con las senalestransmitidas ( 410, 420). Una ganancia de bucle se ajusta sobre la base del estado de propagacion. La ganancia debucle se usa pra ajustar la dimension de los comandos usados para ajustar (es decir, aumentar o disminuir) el parámetro que estásiendo controlad o. Si elestado de propagacion se encuentra en estado de reposo, la ganancia de bucle se fija en 1. Si el estado de propagacion se encuentra en estado depropagacion se encuentra en estado activo, la ganancia de bucle se fija en unvalor mayor que 1, incrementándose así la dimension de los comandos (555, 655)usados para controlar el parámetro. En una realizacion preferida dela presente invencion, el parámetro controlada es una nivel de potencia de transmisionde la primerasenal (410). La pre sente invencion también propone un aparato para ajustar un parámetro de dicha senal de transmision para llevar a lapráctica dicho método.
