摘要：
OFDM signal is very sensitive to frequency offset, it is necessary to estimate the carrier frequency offset. Frequency offset can be divided into two parts: integer frequency offset (IFO) and fraction frequency offset (FFO). The ML algorithm is a good synchronization algorithm, but it cannot estimate the IFO. We design a new method to estimate the IFO based on ML algorithm, which adding position marker to the OFDM sequence. By simulation, IFO estimator has better performance than the conventional method.
