无线定位估计的信息融合模型研究

近年来基于蜂窝网络对移动台进行定位估计的无线定位技术受到广泛的关注,目前的几种基于网络的定位方法在不同的信道和网络环境中表现出的性能各不相同,还没有一种技术能在各种不同信道和网络环境中都能表现出最佳性能,满足对蜂窝网络移动台定位的精度要求。数据融合是一种对不同类型数据进行融合,以取得比单一方法和技术更佳的数据输出的技术。论文将信息融合应用于无线定位之中,对无线定位的信息融合模型进行了深入的研究。

Research on Information Fusion Model For Wireless Location Estimation

In recent years, wireless location technology based on cellular network has been focused. There are several basic location methods based on network that can be used to estimate the position of mobile users. But under the condition of different channel and network, there are different performances for basic location methods. So no single technology has a optimal performance to meet accuracy specification of wireless location in different channel and network environment. Data fusion can be used to integrate different methods and techniques to fuse inhomogeneous data to get a better data output than single methods. In this paper, data fusion technique is used to wireless location, and the model and perfor- mance of data fusion based wireless location are researched in detail.
