在这篇论文中，我们提出一种新的时间偏移估计方法应用于OFDM系统。这里提出的估计是为了避免发生在Schmidl中的时间偏移估计方法中的歧义。通过仿真，所提出方案中的性能以均值和最小均方误差的形式说明。仿真结果表明：它与其它估计器相比在相当大的程度上有更小的均方误差。-In this paper, we propose a new time offset estimation method is applied to OFDM systems. Estimates presented here took place in order to avoid the time Schmidl offset estimation method of ambiguity. Through the simulation, the proposed program of performance to the mean and minimum mean square error of the form. The simulation results show that: it is estimated that compared with the other to a large extent there is a smaller mean square error.
