Abstract

Die Erfindung betrifft ein Verfahren zur Schätzung von Kanalparametern eines zur Übertragung von Nachrichten genutzten Funkkanals in einem Empfänger, in dem eine von einem Sender erhaltene Nachricht dekodiert und einer Schätzung unterzogen wird, wobei zur Bestimmung der geschätzten Nachricht ein Algorithmus eingesetzt wird, wobei die geschätzte Nachricht unter Verwendung von bei der Dekodierung der empfangenen Nachricht ermittelten Dekodierparametern berechnet wird.
