Abstract

Zur Daten-/Nachrichtenübertragung zwischen mindestens einer Basisstation (BS1) und mindestens einer Mobilstation (MS1) eines Funkkommunikationssystems wird das Signal-/Rauschverhältnis (SN1) mindestens eines Testsignals, das von der jeweiligen Mobilstation (MS1) an die zugordnete Basisstation (BS1) gesendet wird, im aktuell vorliegenden Funkkanal (FK) zwischen der Basisstation (BS1) und der jeweilig zugeordneten Mobilstation (MS1) in der Basisstation bestimmt. Aufgrund dieses gemessenen Signal-/Rauschabstandes (SN1) im aktuellen Funkkanal (FK) wird mindestens ein Entzerrparameter (μopt1) für die Vorentzerrung des Funkkanals beim Übertragen von Signalen von der Basisstation an die Mobilstation aus einer bereitgestellten Vielzahl von Entzerrparametern (μ) derart ausgewählt wird, daß die Detektions-Fehlerrate (BER) bei diesem gemessenen Signal-/Rauschverhältnis (SN1) minimal wird. Die Vielzahl von Entzerrparametern (μ) ist dabei unterschiedlichen Signal-/Rauschverhältnissen (SN1 mit SNk) und Detektions-Fehlerraten (BER) zugeordnet sowie in mindestens einem Vorversuch ermittelt und zur Auswertung bereitgestellt worden.
