智能天线研究,然后对LMS算法进行介绍。最后,对智能天线阵列的三种组阵方式进行分析。三种组阵方式分别为均匀线阵、平面阵、均匀圆阵。对三种组阵阵元防线性、阵元位置及其波束形成进行分析。在分析的基础上有matlab对分析结构验证(Research on smart antennas, and then introduced to the LMS algorithm. Finally, the three types of smart antenna array approach to array analysis group. Way array of three groups were uniform linear array, planar array, uniform circular array. Group of three bursts of million line of defense, the array element location and beamforming for analysis. In the analysis based on the analysis of the structure have to verify on matlab)
