Abstract

Verfahren zur Erkennung von als Bit-Folge vorliegenden, zyklisch wiederholten Daten in einem gestörten Radio-Daten-System(RDS)-Signal, bei welchem zur Verringerung der für die Auswertung der RDS-Signale notwendigen Feldstärke des empfangenen Signals ein mehrere Zyklen enthaltender Teil des Datenstroms untersucht und eine statistische Auswertung der einzelnen Bit-Positionen des betrachteten Zyklus' vorgenommen wird und die gesuchten Daten aus dem Ergebnis der statistischen Auswertung abgeleitet werden.

Figure 00000001
Method for recognizing cyclically repeated data as a bit sequence in a disturbed radio data system (RDS) signal, in which, in order to reduce the field strength of the received signal necessary for the evaluation of the RDS signals, a part of the signal containing several cycles Data stream is examined and a statistical evaluation of the individual bit positions of the cycle under consideration is carried out and the searched data are derived from the result of the statistical evaluation.
