摘　　要：研究了TD-SCDMA系统等距线形智能天线阵列的原理,上行链路最大输出功率赋形算法与线性最小约束最小方差波束赋形。搭建上行链路仿真平台,测试了两种波束赋形算法的性能。结果表明,线性最小约束最小方差算法在保证总功率不变的前提下,使得本用户信号的功率最大,因而能够使得干扰用户信号和噪声得到较好地抑制,可以将该波束赋形算法应用于TD-SCDMA系统上行链路。Principle of TD-SCDMA system equidistant linear intelligent antenna array is researched.Uplink maximum output power shaping algorithm and minimal linear constrained minimum variance beamforming is studied.Two kinds of beamforming algorithm is tested based on uplink simulation platform.The results show that linear constrained minimum variance algorithm can make the user signal power maximum in case of unchanged total power,so the user interference signal and noise is well suppressed.the beamforming algorithm can be applied to uplink of TD-SCDMA system.
