针对每个移动终端进行动态的三维波束赋形,为了使三维波束主瓣对准期望用户并且在干扰用户方向形成零陷,构建了均匀平面阵的二维阵列信号模型,研究了基于最小均方误差算法的全局自适应算法,并在此基础上提出了基于降维的局部自适应算法.2种自适应三维波束赋形算法可以动态地调整阵列单元的权值,自适应地改变天线阵列的方向图,为用户提供实时的跟踪服务.仿真结果表明,在一定数量的阵列天线单元的条件下,2种算法均可以实现针对期望用户的自适应三维波束赋形.
For each mobile terminal, the three-dimensional beamforming is performed dynamically. In order to align the main beam of the three-dimensional beam to the desired user and form a zero-collapse in the direction of interfering users, a two-dimensional array signal model of a uniform planar array is constructed. Error algorithm based on the global adaptive algorithm, and based on this proposed a local adaptive reduction algorithm based on the two kinds of adaptive three-dimensional beamforming algorithm can dynamically adjust the weight of array elements to adaptively change the antenna array Which provides users with real-time tracking service.The simulation results show that both algorithms can achieve adaptive three-dimensional beamforming for the desired users under a certain number of array antenna elements.
