Abstract  Abstract

Embodiments are directed to first and second OFDM pilot symbols. The first and second pilot symbols may have first and second sets respectively of allowed forbidden and active carrier frequencies. The second sets of carrier frequencies may be formed by frequency shifting the respective first sets by a predetermined frequency such as the frequency difference between adjacent carriers. An embodiment is directed to frequency translating part of a first received pilot symbol by one carrier interval in a first direction frequency translating part of a second received pilot symbol by one carrier interval in a second direction that is opposite from the first direction and forming a correlation by multiplying the frequency translated parts of the first and second pilot symbols by complex conjugates of parts of the pilot symbols upon which frequency translation has not been performed and summing the multiplication results.
