Abstract

Die Erfindung betrifft ein Verfahren und eine Anordnung zur Erzeugung vorgegebener Richtcharakteristiken von adaptiven Gruppenantennen in drahtlosen Mobilfunksystemen. Es soll eine Lösung angegeben werden, bei der eingehende Störsignale sicher unterdückt werden, eine größere Übertragungskapazität der Funkverbindung erzielt und gleichzeitig die Qualität des Empfangssignals verbessert wird. Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit nachstehend angegebenen Schritten gelöst: Empfang der Nutz- und Störsignale; Bestimmung der Anzahl der eingehenden Signale; Bestimmung der Einfallswinkel der Nutz- und Störsignale durch eine Richtungsschätzung; Trennung von Nutz- und Störsignalen; Begrenzung der Anzahl der Störsignale; Bestimmung der Gewichtsfaktoren (W1-WN) für die einzelnen Signale (X1-XN); Zusammenfassung der mit den Gewichtsfaktoren gewichteten Signale zu einem Gesamtempfangssignal.
