Integrating Interference Localization with Adaptive Nulling Techniques for Communication Satellite

上行干扰会造成卫星通信系统性能严重下降 ,故提出了干扰源定位与自适应调零技术一体化实现的新构想。基于多波束天线的空间谱估计方法可对干扰源进行精确定位 ,利用获取的 DOA估计信息进一步实现干扰信号的有效抑制。应用 MUSIC算法的计算机仿真实验表明该方案是可行的。

This paper brings forth a new idea about integrating interference localization and adaptive nulling techniques against uplink radio frequency interference, which causes severe degradation on the performance of satellite communication system. Spatial spectrum estimation approaches, in conjunction with Multiple Beam Antenna (MBA), are first employed for accurate source localization. This estimated DOA information is then used to achieve adaptive inter...
