| Abstract: | 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. |
