ABSTRACT:
A communications receiver is provided that includes a first and second compensators a pilot tracker and a demodulator. The first compensator is operable to adjust an input signal based on both a coarse frequency offset and a fine frequency offset to produce an adjusted input signal. The pilot tracker determines an estimated residual frequency offset based on at least a portion of the adjusted input signal. The demodulator determines at least a first symbol sequence and a second symbol sequence based on the adjusted input signal. The second compensator is operable to adjust the first symbol sequence and the second symbol sequence based on the estimate residual frequency offset.
