摘    要:跳频通信技术具有较强的抗干扰能力和组网能力,因而得到广泛采用,尤其是在军事通信方面.因此,对跳频通信系统的盲检测也成为通信对抗中的一项重要内容.提出了一种基于频域相关的跳频信号盲检测算法.在不需要任何先验信息的条件下可以对跳频信号进行盲检测.仿真表明该算法在低信噪比条件下具有很好的检测效果.

关 键 词:短波  跳频  自相关  盲检测

Abstract:Frequency Hopping Spread Spectrum(FHSS) communication is widely used,especially in the field of military communication,because of its better ability in anti-interference and net-working,so blind detection signals of FHSS system are considered as important contents in communication counter measures.A blind detection algorithm of FH signal based on the correlation in the frequency domain is proposed.The algorithm can be implemented without any prior information.The effectiveness of the algorithm at low SNR is...
Keywords:HF frequency hopping autocorrelation blind detection
