| 摘 要： | 同步是OFDM（Orthogonal Frequency Division Multiplexing）系统的关键技术之一。使用重复的PN（pseudo-noise）序列和循环前缀作同步的新方法,与仅利用循环前缀的方法相比,有估计精度高和范围大的优点。在给出其推导过程的基础上给出了仿真结果,证明了分析的正确性。

| Abstract: | Synchronization is one of the key technology for orthogonal frequency division multiplexing systems.A new Synchronization method that uses repeated pseudo-noise sequences and cyclic prefix is proposed in this paper.Compared with the method that only uses cyclic prefix,the proposed method has more precise estimation and 1arger estimation range.The computer simulations show that this synchronization algorithm has a good performance. |
