Abstract

Bei einem Verfahren und einer Vorrichtung zur automatischen Frequenzregelung in einem W-CDMA-Empfänger wird eine Frequenzverschiebungsmessung über einen gewissen Zeitabschnitt gemittelt. Wenn die zu mittelnde Messung eine Rahmengrenze schneidet, so werden an der Rahmengrenze die Teilergebnisse der Messung nicht verworfen, sondern eine zum Zwecke der Mittelung laufende Integration wird nur unterbrochen und dann wieder aufgenommen, sobald wieder genügend und korrekte Daten verfügbar sind.
