| 摘 要： | 建立了干扰条件下的接收信号模型,提出了干扰抑制方案。利用信号谱包络的相似性,给出了基于滑动窗最小二乘的干扰盲检测方法,进而根据对消的思想消除窄带干扰。仿真结果表明该方法能有效抑制DSSS卫星通信中常见的窄带干扰。

| Abstract: | After building receiving signal model under narrowband interferences,a suppression scheme is proposed.From similarity of signal spectrum envelope,blind detection method based on least square technique of sliding window is presented.Then,narrowband interferences can be effectively rejected from the idea of corresponding elimination.Simulation results show that the algorithm can effectively reject common narrowband jamming in DSSS satellite communication. |
