| 摘 要： | 随着第三代(3G)移动通信的发展和美国E911规定的颁布,蜂窝网络移动台(MS)无线定位技术得到了越来越广泛的注视.该服务能够提供有关移动台位置的信息,因此在很多领域有着重要的应用.提出了一种基于到达时间差(TDOA)的三维定位算法.其主要思想是用一新变量代替定位估计中的二次项,把非线性估计转化为两次WLS(加权最小二乘)线性估计.此算法结构简单,计算量较小.通过模拟仿真,结果证明了该算法的有效性.

| Abstract: | With the development of the third generation(3G) mobile communication systems and the release of the emergent 911(E911) call in USA,cellular radio location technology for the mobile station(MS) has been broadly focused more and more.Because the service can provide the position information about MS,the location technology plays an important role in many fields.A 3-dimension location algorithm based on TDOA(time difference of arrival) is proposed.By using a new variable to replace the square term,the nonlinea... |
