基于小波包分析的跳频通信盲窄带干扰自适应抑制方法OA

The traditional frequency hopping communication blind narrowband interference adaptive suppression method directly on the interference signal wavelet packet decomposition did not model the frequency hopping communication blind narrowband interference signal,resulting in the traditional method of interference suppression effect is poor.Therefore,this paper proposes an adaptive suppression method for blind narrowband interference of frequency hopping communication based on wavelet packet analysis.The blind narrowband interference signal of frequency hopping communication is modeled to enhance the interference suppression ability,the interference signal is decomposed by wavelet packet,and finally the blind narrowband interference adaptive suppression of frequency hopping communication is realized based on wavelet packet analysis,and comparative experiments are designed,and the experimental results show that the research method has a significant advantage of stronger interference suppression effect.
