Abstract The OFDM transmitter diversity has gotten more attention in recent years. However, OFDM systems are very sensitive to frequency-offset. Therefore, it is necessary to estimate effectively and to compensate frequency-offset in the systems. This paper presents a blind and adaptive fine frequency-offset estimation method firstly, and then proposes a coarse frequency-offset estimation method based on pilot frequency. Finally, simulation results verify these methods.
