| 摘 要： | 针对传统的频率同步方法中估计精度与估计范围的矛盾,提出了一种改进的频率同步算法。该算法通过两次频率偏移估计,可以同时获得大的估计范围和高的估计精度,而且对训练序列没有其他限制,可以提高系统数据传输效率。通过仿真,验证了该算法的有效性。

| Abstract: | Aiming at the inconsistency between estimation range and estimation precision in the traditional frequency synchronization algorithm,a new frequency synchronization method is introduced.Large estimation range and precise estimation can be acquired by the new method by twice frequency offset estimation;moreover,date transmission efficiency will be improved without any demand for training sequences.The validity of the new algorithm is verified by computer simulation. |

| Keywords: | orthogonal frequency division multiplexing frequency synchronization training sequences |
