Patent ID: 8098567

Claim:
A method for timing correction in a communication system comprising: adjusting, by a transceiver, a time basis of one or more pilot interlaces and combining the one or more pilot interlaces, wherein adjusting the time basis of the one or more pilot interlaces includes changing phases of one or more pilot tones of the one or more pilot interlaces to correct for changes in frequency, and wherein changing the phases of the one or more pilot tones comprises: performing, by a rotator in the transceiver, a sequence of rotations of at least one pilot tone through a number of phase rotations; and performing, by the rotator in the transceiver, a single rotation of the at least one pilot tone where the single rotation is equivalent to the number of phase rotations; matching, by a channel estimator in the transceiver, the time basis of the combined pilot interlaces with a symbol to be demodulated; and obtaining, by the channel estimator in the transceiver, a corrected channel estimate based on the combined pilot interlaces having a time basis matching the symbol.
