摘要
对基于数字波束形成技术的智能天线接收系统中的空间干扰抑制算法进行研究,实现天线系统的最佳接收。运用多重信号分类(MUSIC)算法检测信号和干扰方向,并利用改进的线性最小方差准则算法调整权系数,使接收系统实时跟踪信号和干扰的空间方向,并能进一步加宽波束的干扰零陷,提高系统的空间干扰抑制能力。
Baesed on digital beamforming technology, the spatial interfenee suppressive algorithm are researched to re- alize optimal receving in smart antenna system. The MUSIC algorithm is used to estimate the direction of useful and interference signals. The optimize weighted value are geted by the improved LCMV algorithm. So that, the antenna system can trace the direction of signals on time. Bsides, the improved LCMV algorithm can increase nulling width and improve the capacity of spatial interferenee suppression.
