ABSTRACT:
In a receiver employing complex correlation, there is provided a mechanism for carrier frequency offset equalization. There exists a linear phase progression in the correlation process that is indicative of frequency offset. One method involves curve fitting the phase progression in order to warp the sync word against which subsequent correlation is performed rather than controlling the reference frequency of the receiver. The other successively approximates the phase progression by pre- and re-warping the synchronization reference word within the correlation process itself rather than controlling the reference frequency of the receiver.
