        OFDM synchronization using PN Correlation and initial cross-correlation:
        F. Tufvesson, O. Edfors, and M. Faulkner, "Time and Frequency Synchronization for OFDM using
        PN-Sequency Preambles," IEEE Proc. VTC, 1999, pp. 2203-2207.

        This implementation is meant to be a more robust version of the Schmidl and Cox receiver design.
        By correlating against the preamble and using that as the input to the time-delayed correlation,
        this circuit produces a very clean timing signal at the end of the preamble. The timing is
        more accurate and does not have the problem associated with determining the timing from the
        plateau structure in the Schmidl and Cox.

        This implementation appears to require that the signal is received with a normalized power or signal
        scaling factor to reduce ambiguities introduced from partial correlation of the cyclic prefix and
        the peak detection. A better peak detection block might fix this.

        Also, the cross-correlation falls apart as the frequency offset gets larger and completely fails
        when an integer offset is introduced. Another thing to look at.
