摘要
为了有效地抑制来自跳频卫星通信系统上行链路的快速跟踪干扰 ,本文提出了一种数字波束形成与跳频相结合的新型干扰抑制技术 (AJDBFFH) .基于AJDBFFH技术 ,本文较好地解决了快速跟踪干扰与跳频有用信号相关所带来的干扰抑制问题 .通过对快速跟踪干扰抑制的计算机仿真 ,其结果表明 ,AJDBFFH技术可以有效地抑制快速跟踪干扰 ,系统的误码率性能得到了明显的改善 .
In order to effectively suppress the fast follower jammer from up-link in frequency-hopping satellite communication systems,a novel jamming suppression technique (AJDBFFH) of combining digital beamforming(DBF) with frequency-hopping(FH) is presented.The jamming suppression problem of signal correlation between the fast follower jammer and the desired signal is solved by using AJDBFFH technique.Computer simulation results show this technique against the fast follower jammer is very effective and the error bit rate performance is improved.
