摘　　要：本文通过使用智能天线,给出高性能的层次化CDMA移动通信网络的设计策略。重点是对大区到小区所需的功率分析,大区智能天线模式分析以及小区天线倾斜角度对系统性能提高的影响。结论表明系统性能取决与小区位置和天线倾斜角度。通过定义干扰平衡因子得到最优的小区天线倾斜角度。In this paper,we present hierarchical cell deployment strategies for designing a high capacity cellular mobile radio system by using smart antennas. The focuses are on the ratio of required receive power of macrocell to that of the microcell ,smart antenna patterns of macrocell and the tilt angle of the microcell antenna to increase the system capacity, We show the system capacity is dependent on the tilt angle.The optimal tilt angle of microcell are obtained by defining the interference trade-off factor that will be used to maximize the capacity.
