Abstract

Verfahren zur Kanalentzerrung von Empfangsdaten, die über einen Übertragungskanal (H) übertragen werden, mit den folgenden Schritten: Empfangen (S1) der Empfangsdaten in einem Empfangsdatenpaket; Bestimmen (S2) von Kanalparametern des Übertragungskanals (H) aus den Empfangsdaten (Xk) und Speichern der Kanalparameter in ein Datenfeld (D); Berechnen (S3) von Filter-Einstellkoeffizienten (p) eines Vorfilters (P) und von Entzerrer-Einstellkoeffizienten (g) eines Entzerrers durch GIVENS-Rotation des Datenfeldes (D); Einstellen (S4) des Vorfilters (P) und des Entzerrers mit den berechneten Koeffizienten (p, g); Entzerren (S5) der Empfangs daten durch das eingestellte Vorfilter (P) und den eingestellten Entzerrer.
