摘要
随着定位技术的不断发展,如何实现室内精确定位逐渐成为研究的热点.在复杂的室内环境下,信号的传输受到各种因素的影响,将会产生多径效应,进而影响定位效果.通过利用通用设备的多输入多输出(MultipleInput Multiple-Output,MIMO)系统特性及室内多径效应,采用信道状态信息(Channel State Information,CSI),设计被动式室内定位方案,从而达到室内被动式定位功能.实验结果表明:对比相应的基于接收信号强度(Received Signal Strength,RSS)方案,本文提出的方案具有较低的定位误差.
How to realize the indoor precise localization gradually become a hot research with the continuous development of localization technology. The signal transmission is affected by various factors, which will produce the multi-path effect, and then influence the localization effect in the complex indoor environment.By utilizing the characteristics of Multiple-Input Multiple-Output（MIMO） system and indoor multipath effect, State Information Channel（CSI） is adopted to design the passive indoor positioning scheme, which can achieve the indoor device-free passive location.The experimental results show that the proposed scheme of the proposed scheme has lower error than the Signal Strength Received（RSS） scheme.
