提出了两种用于正交频分复用（OFDM）系统的定时偏置估计方法，作为Schmidl和Cox方法的改进。根据仿真得到的估计量方差，比较了加性高斯白噪声信道和码间干扰信道中时间偏移估计器的性能。这两种方法在两种信道条件下都具有显著较小的估计方差。
Two timing offset estimation methods for orthogonal frequency division multiplexing (OFDM) systems as modifications to Schmidl and Cox's method [6] are presented. The performances of the timing offset estimators in additive white Gaussian noise channel and intersymbol interference channel are compared in terms of estimator variance obtained by simulation. Both proposed methods have significantly smaller estimator variance in both channel conditions.
