摘要
在WCDMA网络环境下,提出一种基于单定位台的新型被动式定位技术—椭圆-双曲线混合定位,它利用信号到达时间和(TSOA)与到达时间差(TDOA)完成对目标的定位.在非视距(NLOS)环境下,利用Chan算法估计的目标位置作为迭代初始值,再通过Taylor级数展开法求解定位方程组.仿真结果表明,在NLOS下,该算法性能明显优于Chan算法,近似于采用真实目标位置的Taylor级数展开算法的性能,有较高的实用价值.
Abstract
This paper presents new locating technology called ‘Hybrid Ellipse-Hyperbola location' with single equipment in WCDMA cellular net-works,which use the measurements of TSOA and TDOA to locate the mobile user.The algorithm uses Taylor series expansion to solve the locating equations and the initial estimation is provided by Chan algorithm,in NLOS Environment.The simulation result indicates that this proposed algorithm has higher accuracy than Chan algorithm and its performance is comparable to the Taylor series expansion method based on true position as initial estimation.
