| 摘 要： | 目前TD-SCDMA系统多采用智能天线和上行同步技术对移动用户的位置信息进行联合估计。现有的智能天线技术在测角过程中,空间谱搜索计算量大且用户定位容量受到天线阵元数目的限制。针对上述缺点,提出一种用户数目不受限制的快速定位算法。新算法主要利用Midamble码的非相关特性对角度估计算法进行了改进。仿真实验证明了该算法的有效性。 |

| Abstract: | The estimation of the users′ location is based on smart antenna and uplink synchronization in TD-SCDMA.Considering the large computation and users number limitation of spatial spectrum searching,the existing smart antenna technology does not adapt to the requirement.Therefore,a new non-limited algorithm with less computational complexity is proposed.The direction vector of the users can be estimated by decorrelation of the midambles of users,and then the Direction of Arrival（DOA） of the users can be computed owing to the receiving array manifold.The excellent performance of the new technique is verified through experimental simulation. |
| Keywords: | TD-SCDMA location direction of arrival intelligent antenna |
