| 摘 要： | 到达时间差(TimeDifferenceofArrival,TDOA)位置估计是无线定位的一项关键技术.首先介绍了TDOA定位估计原理,阐述了基站任意分布时(以三基站为例)的二维定位估计,以及在特殊情况下,即基站线性分布时的定位估计.最后,对三基站TDOA定位估计及其定位精度进行了仿真,为第三代移动通信无线定位系统的研究和开发提供了理论基础.

| Abstract: | The estimation for TDOA location is a key technology of wireless location. In this paper, the estimation principles for TDOA location are introduced first. Then the 2-D estimation for wireless location while BSs(Base Stations) are in arbitrary array (for example, three BSs) and specially, the estimation for wireless location while BSs are linear arrayed are mainly discussed. Finally, the estimation and precision for TDOA location are simulated. Therefore, a theory basic is given for the research and development of the wireless location in the third generation mobile telecommunication system. |
