本文对扩展频谱通信系统中采用自适应陷波器抑制单频强干扰的性能进行了分析,对自适应陷波器的工作情况进行了计算机模拟。结果表明了自适应陷波器抑制单频强干扰的良好效果,它的信干比改善因子与干扰的领率无关,并随着输入信干比的减小而增大。 In this paper, the performance of adaptive notch filter to suppress single frequency strong interference in spread spectrum communication system is analyzed, and the working of adaptive notch filter is simulated by computer. The results show that the adaptive notch filter has a good effect of suppressing the single-frequency interference. The improvement factor of the SINR has nothing to do with the jamming rate, and increases with the decrease of the SINR.
