UWB Indoor Localization System
by Gao, Xiangjian, M.S., The George Washington University, 2018, 177; 10813674
Abstract (Summary)

本论文介绍了超宽带传输系统和超宽带在室内定位系统的应用. 首先, 本论文介绍了已经存在的室内定位技术并比较它们的优缺点. 之后, 本论文分开介绍超宽带传输系统的结构(传输机, 信道, 接收机) 和运营机制. 接下来, 根据超宽带传输系统的运营机制, 介绍不同的定位算法. 本文主要研究TOA定位算法, 分别介绍了信号互相关接收机和能量检测接收机的工作原理. 再然后, 本论文介绍了最小二乘算法和权重最小二乘算法去解非线性方程组来得到标签的位置. 本论文对于系统在2D和3D的地图上做了Matlab模拟图, 并对生成图进行了比较和介绍. 最后, 本论文介绍一种根据IEEE 802.15.4a信道做的经验式NLOS环境时延消除, 根据本文的系统流程图进行10000次的模拟, 对于定位误差有了明显的改进, 平均定位误差为7cm.
