Abstract

Die Erfindung betrifft ein Verfahren zur Signalübertragung in einem Funkkommunikationssystem, bei dem von einer Basisstation (BS) mittels einer ersten adaptiven Antenneneinrichtung Signale gesendet werden. Die von der Basisstation (BS) gesendeten Signale werden durch eine Sende-/Empfangseinrichtung (MT1, MT2) mittels einer zweiten adaptiven Antenneneinrichtung empfangen. In einer Signalverarbeitungseinrichtung (DSP1, DSP2) werden diskrete Doppler-Verschiebungen für die mittels der zweiten adaptiven Antenneneinrichtung empfangenen Signale ermittelt. Zu den mittels der zweiten adaptiven Antenneneinrichtung empfangenen Signalen gehörige Originärsignale werden anhand der ermittelten diskreten Doppler-Verschiebungen rekonstruiert. Die rekonstruierten Originärsignale werden über eine drahtlose und/oder drahtgebundene Schnittstelle (IF1, IF2) von der Signalverarbeitungseinrichtung (DSP1, DSP2) zu mindestens einer Teilnehmerstation (UE1-UE4) übermittelt.
