提出了一种新的基于前导码的正交频分复用（OFDM）系统定时偏移估计方法。该方法具有鲁棒性强、不受载波频偏影响、与前导码结构无关等优点。在多径衰落信道中，通过仿真得到的均方误差（MSE）证明了新方法的性能。结果表明，与现有方法相比，新方法显着提高了定时性能。
This study presents a novel preamble‐based timing offset estimation method for orthogonal frequency division multiplexing (OFDM) systems. The proposed method is robust, immune to the carrier frequency offset (CFO), and independent of the structure of the preamble. The performance of the new method is demonstrated in terms of mean square error (MSE) obtained by simulation in multipath fading channels. The results indicate that the new method significantly improves timing performance in comparison with existing methods.
