| 摘 要： | 在分析以往算法的基础上,提出了一种改进的定时同步算法。它克服了以往算法的缺陷,所采用的自相关算法对频率偏差具有较强的鲁棒性。仿真分析表明该算法在多径信道中其性能仍然较好。提出的算法比较简单,而且开销较低。

| Abstract: | An improved timing algorithm is proposed in this paper and the proposed algorithm overcomes the shortcomings of the conventional method.Because autocorrelation is used in algorithms,timing recovery of the proposed is robust to carrier frequency offset and multipath.The proposed algorithm is simple and the overhead is small. |
