Abstract
Methods and apparatuses of the invention are directed to correcting errors caused by frequency offsets between clocks in a communication system, for example SFO. According to certain aspects, embodiments of the invention provide for resampling data samples corresponding to a received data symbol immediately prior to performing an FFT. According to certain additional aspects, the resampler operates only on the data samples of a cyclic data block, with a known (and minimized) sample timing error to correct.
