description The present invention relates to a method and a device for data extraction from a data stream containing at least one data packet. First, comparing a bit stream derived from a received digital data stream with an expected bit sequence is performed by packet detector to determine a correlation value (CorrVal) for detecting a data packet. Then, a data extraction unit is started for data extraction when the correlation value (CorrVal) exceeds a threshold value (CorrThres) indicating that a data packet has been detected. Therefore, comparing the received bit stream with the expected bit sequence to determine a new correlation value (CorrVal) is continued by the packet detector. Finally, restarting data extraction is initiated by a sync-control module when the new correlation value (CorrVal) exceeds the form correlation value (MaxCorrVal).
