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. 在符號同步的基礎上，利用消去新訓練符號中偽隨機加權因子的數據序列進行頻偏估計。
Simulation results show that the accuracy of timing synchronization and the estimate range of the frequency offset outperform those of the other available methods. 模擬結果表明所提方法的符號同步偏移估計精度和頻偏估計範圍均優於已有的同步方法。
