一种多用户波束优化设计的分析与仿真

智能天线技术可以在提高移动通信服务容量和质量的同时而不占用更多的频谱资源。文中就一种利用切比雪夫天线阵来实现智能天线下行波束的优化设计进行了详细分析和仿真。理论分析和仿真结果表明，与其它方法相比，该方法具有空间分辨率高，同信道干扰可控，且计算量小，鲁棒性好，用户波束个数不受阵元个数限制的优点。

Analysis and simulation of multi - user optimum beamforming

Smart antenna technology gave a solution for the increasing capacity and quality demands for mobile communication services without a corresponding increase in RF spectrum allocation.In this paper,an optimum design of downlink beamforming in the smart antenna system based on Chebyshev array is put forward.The theoretical analysis and the result of simulation show that,compared with other methods,this method has obvious advantages of higher spatial resolution,controllable co-channel interference,lower computational complexity,better robustness,the number of output ports is not limited by the number of antenna elements.
