Based on the timing synchronization, the PN weighted factor in the training symbol is removed, and the renewed training symbol is used to estimate the frequency offset. 在符号同步的基础上，利用消去新训练符号中伪随机加权因子的数据序列进行频偏估计。
Simulation results show that the accuracy of timing synchronization and the estimate range of the frequency offset outperform those of the other available methods. 仿真结果表明所提方法的符号同步偏移估计精度和频偏估计范围均优于已有的同步方法。
