信道状态信息无线感知数据获取及应用综述

近年来，基于信道状态信息（CSI）的无线感知技术在室内定位、活动识别、健康检测等方向有众多探索性研究应用。然而，现有研究获取CSI数据主要依靠自主采集，对CSI开源数据集和数据采集设备/工具的研究现状不够清晰。首先阐述了基于无线保真（WiFi）CSI的无线感知技术，详细介绍了9种CSI数据采集设备/工具，概括了CSI的应用方向及研究现状，并汇总了近5年的CSI开源数据集，分析了现有CSI无线感知研究的局限性与面临的挑战，最后总结全文并对CSI无线感知未来的发展进行展望。

A survey on data acquisition and application of channel state information wireless sensing

In recent years, wireless sensing technology based on channel state information (CSI) has been extensively and exploratorily studied and applied in several directions, such as indoor positioning, activity recognition, and health monitoring. However, the current research primarily relies on the independent collection of CSI data, and presenting a lack of clarity towards the research status of CSI open-source dataset and data acquisition devices/tools. Firstly, the wireless sensing technology based on wireless fidelity (WiFi) CSI is described. Secondly, 9 types of CSI data acquisition devices/tools are introduced in detail and the application directions and research status of CSI are generalized. Thirdly, the CSI open-source datasets of the past five years are aggregated and the limitations and challenges of current research on CSI wireless sensing research are analyzed. Finally, the content of the full text is summarized and the future trend of CSI wireless sensing is prospected.
