摘要: 介绍了单载波频域均衡(Single Carrier system with Frequency Domain Equalization,SC-FDE)系统中的定时同步问题,提出了一种新的定时捕获算法。算法仅使用一帧辅助数据就可以完成定时捕获,并对算法的可靠性进行了仿真。结果表明,该算法较好地解决了SC-FDE系统的接收端的定时捕获问题。

Abstract: A new timing acquisition algorithm is proposed that can estimate the timing offset using only one training frame.This algorithm is intrinsically robust to multipath channel.The proposed algorithm has much better precision and fewer computations.Simulation results show that the method can solve the synchronization question in the SC-FDE system.
