Abstract By analyzing the OFDM signal, a carrier frequency offset estimation algorithm for uplink of OFDM systems is proposed. The algorithm with high accuracy can be imple-mented easily, and the performance of the algorithm is almost not affected by the sub-carrier number per user, which makes the algorithm suit for the multi-user OFDM system. The simulation shows that the algorithm has a better performance than the algorithm based on cyclic prefix.
