| 摘 要： | 传统的双门限窄带干扰抑制算法存在不能自适应处理大信噪比动态范围接收信号的问题.作者在双门限算法的基础上,提出了自适应三门限窄带干扰抑制算法的基本思想,并结合系统参数研究了门限系数选取方法、干扰检测与抑制方法.仿真结果表明该算法具有优良的抗干扰性能.

| Abstract: | Traditional dual threshold narrowband interference suppression algorithm cannot adaptively process received signal with large SNR dynamic range.Based on dual threshold algorithm,the basic idea of adaptive tri-threshold narrowband interference suppression algorithm was proposed.Combining system parameters,threshold coefficient selection method,interference detection and suppression method were studied.Simulation results show that this algorithm has excellent anti-jamming performance. |
