| 摘 要： | 在最大相关算法和集相关算法的基础上,提出了一种基于循环前缀的OFDM定时同步新算法.该算法具有计算复杂度低,估计性能好的优点.仿真结果表明,无论在高斯信道,还是在多径衰落信道条件下,该算法性能均优于单纯最大算法或集相关算法.

| Abstract: | Based on the maximum correlation and ensemble correlation methods, a new method of OFDM system timing synchronization based on cyclic prefix is proposed. The new method has higher performance and lower computation cost. The simulation results show that the performance of timing synchronization is better than that of the maximum correlation or ensemble correlation methods over wireless muhipath channel. |
