Gain control method and device for a bursty data frame reception system

Methode et dispositif de commande de gain pour un système de réception de trame de données par pacquets

Verstärkungsregelungsverfahren und Vorrichtung für ein Burst-Datenrahmen-Empfangssystem

Abstract

The gain control method for the RF and IF amplification stages of a bursty data frame reception system enables, following a step for evaluating the received signal strength, the gain adjustment step of the RF amplification stage to be temporarily deferred until a frame structure symbol is received, during which the gain adjustment step of the IF amplification stage takes place simultaneously with that of the RF gain, while retaining an overall gain linearly dependent on the input signal strength. The corresponding device comprises a control element 46 which generates the control signal for the RF and IF gain amplifiers.
