Abstract

Es ist eine Verstärkeranordnung sowie ein Empfänger mit der Verstärkeranordnung angegeben, wobei der Verstärker (5) einen Programmiereingang (6) zum Einstellen der Verstärkung hat. Mit einem Vergleicher (8) wird der Signalpegel am Ausgang des Verstärkers (5) mit einem Referenzpegel (REF) vergleichen. Ein Zähler (10) wird schrittweise inkrementiert und dadurch die Verstärkung im Verstärker (5) so lange reduziert, wie der Ausgangspegel (OUT) über dem Referenzpegel (REF) liegt. Mit dem beschriebenen Prinzip können bei Frequenzsprungverfahren auftretende, frequenzabhängige Empfangsfeldstärkeschwankungen in Abhängigkeit der Verhältnisse im aktuellen Zeitschlitz ausgeregelt werden. Das vorgeschlagene Prinzip ist insbesondere für solche Modulationsverfahren geeignet, bei denen eine Modulation mit Phasen- und Amplituden-Variation verwendet wird.
