翻译：针对非协作突发通信情景下，接收端需要利用帧同步盲识别技术来完成对有用信息的提取，这对于截获信号的分析具有十分重要的意义。而传统的帧同步码盲识别方法需要先将数据完全解调再识别帧同步码，其计算量太大，复杂度过高。因此，本文提出了一种基于调制信号时域特征的帧同步盲识别方法。

Translation: In non-collaborative emergency communication scenarios, the receiver needs to use frame synchronization blind recognition technology to extract useful information, which is of great significance for analyzing intercepted signals. However, traditional frame synchronization code blind recognition methods require complete demodulation of data before recognizing the frame synchronization code, which results in excessive computational complexity. Therefore, this article proposes a frame synchronization blind recognition method based on the time-domain characteristics of modulated signals.
