提出一种基于相位信息和实部检测的OFDM盲帧同步方法。该方法对接收信号做同步处理时只保留原信号的相位信息,并仅对滑动相关的实部进行检测以完成基于循环前缀的盲同步,通过仿真与现有方法进行了相应对比,证明该方法能获得更高的定时同步精度。
A new method for blind coarse frame synchronization is proposed, which only uses phase information of the received OFDM signal and introduces real detection to obtain cyclic-prefix-based blind coarse frame synchronization. The proposed method is compared with traditional methods by simulation which shows that the new method can obtain a more accurate synchronization of OFDM symbols.
