摘要
针对正交频分复用系统(OFDM)对同步偏差的敏感性,提出一种新的数据辅助算法.该算法通过利用Schmidl&Cox训练序列,重新设计定时测度函数,有效地克服了传统数据辅助型算法的缺陷.通过仿真表明,该算法可以有效的改进传统算法在多径信道下性能.
In order to overcome the serious influence of synchronization offset on OFDM sys- tems, a novel synchronization algorithm for OFDM systems was proposed. The method used the Schmidl＇ s preamble and proposes a new timing metric. The proposed method timing al- gorithm eliminated the defect in conventional method effectively. The performances of the frame synchronization methods in multipath channel were compared in terms of MSE obtained by simulations. It could be seen from the simulation result results that the proposed methods had the better performances than conventional methods.
