In cooperative OFDM system, because of the OFDM technology, cooperative communication system is very sensitive to carrier frequency offset, a tiny carrier frequency offset will cause the inter-carrier interference. An estimation algorithm of carrier frequency offset based on signal reconstruction is proposed in this paper, the value of carrier frequency offset is estimated by the tracking algorithm, and the estimation algorithm can adjust the action of system in real-time. Through the simulation, it indicated that the estimation algorithm proposed can track the change of carrier frequency offset correctly, and make appropriate adjustment quickly. Generally speaking, it has advantages of rapider response and more accurate estimation.
