1. A method in a wireless communication device for correcting a frequency error of a signal, the method comprising:

  • receiving a signal;

    correlating the received signal with a plurality of offset prestored data sets;

    generating at a predetermined data rate interval a plurality of signal correlations, each of the plurality of correlations correlated to each of the plurality of offset prestored data sets; and

    computing a frequency error estimate based upon the plurality of signal correlations.
