%X In this paper a new frequency offset estimation method using repeated sequences is introduced where two steps are involved. In the first step the span of the correlation data is small and a larger estimation range can be achieved. After the frequency offset is compensated, a larger correlation data span is chosen and a precise estimation can be got. Large estimation range and precise estimation can be acquired in the new method. Simulations in AWGN channel and Rayleigh channel verify the validity of the new algorithm.
