| Abstract: | In order to synchronize the carrier frequency quickly and accurately, the design of the estimation algorithm of large frequency offset based on the arc-cosine function is proposed in this paper. With the theoretical derivation, the estimation algorithm is given. At last with the simulation by matlab, the good performance with anti-noise and high- accuracy is revealed. |
