摘要
强干扰环境下的无线拼接组网是恶劣环境下组网应用的难点所在。传统方法通常采用盲信号分离算法以及普通小波噪声分离对噪声及干扰进行抑制,但是效果并不理想。提出一种强干扰下基于临界跨越分析算法的无线拼接组网技术,首先对组网呼叫信号与噪声进行分离计算,再对处理后的信号进行白化、临界跨越分析,从而提高系统抗干扰能力,实现可靠组网。在实际恶劣环境下进行仿真实验,结果表明采用临界跨越分析算法,系统的组网干扰分布得到了很好的抑制,组网系统具有很好的抗干扰能力,可以被广泛应用。
It was the most difficult for the wireless network application in strong interference environment. In conventional method, the common blind signal separation algorithm was used as well as ordinary wavelet noise separation on noise and interference suppression, but the effect was not ideal. So a wireless network stitching method with across critical analysis in high interference was proposed, firstly, the signal was calculated with wavelet noise separator, and then the processed sig-nal after whitening was calculated across critical analysis to improve anti-jamming capability. The actual simulation experi-ment result shows that with across critical analysis algorithms, the distribution of network interference suppression is better than traditional method, network system has good anti-jamming capability, and which can be widely used.
