| 摘 要： | 针对低干信比和复杂动态情况下传统的干扰检测算法效率不高的问题,提出一种基于盲通信信号频域处理的未知干扰自动检测算法。该方法首先借助快速独立成份分析(FICA)从频谱差分数据中分离干扰和通信信号成份分量,然后利用各分量的峰度作为干扰与通信信号的识别特征检测干扰。实验结果表明,此算法能有效地在干信比小于5 dB的情况下从盲通信信号背景中自动提取未知干扰的信息,实现高精度地盲干扰检测。

| Abstract: | Conventional jams detection methods are inefficient under low SNR and complicated condition.To solve the problem,the paper presented an algorithm for blind jams auto-detecting from communication signal based on spectrum data.This method started by separating the jams and signal components present in the spectrum data cube using a Fast ICA(FICA) based algorithm.The resulting components were ranked according to the feature of kurtosis value and recognizing jams.It is proved that this algorithm can extract the... |
