摘要
为了提高蜂窝网中对移动台(MS)的定位精度,在文献[1]中,Kleine-Ostmann提出了一种对电波到达时间(TOA)和到达时间差(TDOA)测量值进行融合的模型。本文对该模型进行了改进,增加了AOA测量值的使用,提出了融合度更高的增强型数据融合模型。分析和仿真结果表明,只要AOA测量值达到一定精度要求,该模型就能取得更好的定位性能。
In order to improve the location accuracy to mobile station in cellular networks, in reference [1], Kleine-Ostmann proposed a data fusion model to fuse TDOA and TOA data. In this paper, Kleine-Ostmann抯 model is enhanced by employing AOA measurement and an extended data fusion model with higher degree fusion is proposed. It is shown by analysis and simulation that as long as AOA measurement is relatively accurate, better location performance can be achieved by this model.
