针对OFDM技术对系统的时钟同步要求非常高的问题，提出了一种新的采样频偏盲估计算法，该算法可较好地解决估计精度和估计复杂度的折中问题。通过仿真结果表明，在高斯白噪声信道下，与同类算法相比，该算法不仅估计精度高，而且估计复杂度低，符合实际工程应用。

In the light of highly strict timing synchronization for OFDM technology, a new sampling frequency offset (SFO) estimation algorithm has been proposed in this paper which has a good tradeoff between complexity and precision. Simulation results show that compared with similar algorithms, the proposed algorithm not only has high estimation precision, but has low complexity as well in AWGN channel.
