1. A method comprising:

  • comparing a bit stream derived from a received digital data stream with an expected bit sequence to determine a correlation value for detecting a data packet;

    starting data extraction from the bit stream when the correlation value exceeds a threshold value to indicate that a data packet has been detected;

    storing the correlation value that exceeds the threshold value as a maximum correlation value for use as a new threshold value;

    continuing comparing the bit stream with the expected bit sequence during started data extraction to determine a new correlation value; and

    restarting data extraction from the bit stream when the new correlation value exceeds the stored maximum correlation value.
