Abstract
A frequency offset may be determined by detecting phase information for both a one-symbol difference and a two-symbol difference of a received known signal. Half a value representing the phase information detected for the two-symbol difference is averaged, for a particular interval, with a value representing the phase information detected for the one-symbol difference. The frequency offset is determined from the average.
