IEEE 802.11AX CSI Dataset for Human Activity Recognition
收藏资源简介：
The dataset includes channel frequency response (CFR) data collected through an IEEE 802.11ax device for human activity recognition. This is the first dataset for Wi-Fi sensing with the IEEE 802.11ax standard which is the most updated Wi-Fi version available in commercial devices. The dataset has been collected within a single environment considering a single person as the purpose of the study was to evaluate the impact of communication parameters on the performance of sensing algorithms. Three activities have been considered -- walking and running around the room, and staying in place -- and the data in the empty space scenario has also been recorded and made available as part of the dataset. The evaluation has been performed by using the state-of-the-art SHARP algorithm and is presented in the article "Toward Integrated Sensing and Communications in IEEE 802.11bf Wi-Fi Networks" accepted for publication in IEEE Communications Magazine. The CFR data has been collected over an 80 MHz bandwidth channel on the 5 GHz band. For each available OFDMA sub-channel, the complex-valued channel data is recorded. Overall CFR data is available for the 996 OFDMA data sub-channels out of the 1024 sub-channels available (the remaining ones are control sub-channels where the channel reading is not available.If you find the project useful and you use this dataset, please cite our article:@article{meneghello2023toward, author = {Meneghello, Francesca and Chen, Cheng and Cordeiro, Carlos and Restuccia, Francesco}, journal={IEEE Communications Magazine}, title = {{Toward Integrated Sensing and Communications in IEEE 802.11bf Wi-Fi Networks}}, year = {2023}, volume={}, number={}, pages={} }
本数据集包含通过IEEE 802.11ax设备采集的信道频域响应（Channel Frequency Response, CFR）数据，用于人体活动识别。这是首个面向商用设备中最新版Wi-Fi标准IEEE 802.11ax的Wi-Fi感知数据集。本次数据采集在单一实验环境中完成，因本研究旨在评估通信参数对感知算法性能的影响，故仅选取单一人作为受试者。本次实验涵盖三类活动：在房间内行走、奔跑以及原地静止，同时还采集并公开了空无受试者场景下的相关数据，作为数据集的组成部分。本数据集已通过当前主流的SHARP算法开展性能评估，相关评估结果已发表于被《IEEE Communications Magazine》接收的论文《面向IEEE 802.11bf Wi-Fi网络的感知与通信一体化研究》。本次CFR数据采集于5GHz频段的80MHz带宽信道，针对每个可用的正交频分多址（Orthogonal Frequency Division Multiple Access, OFDMA）子信道，记录复数值信道数据。在1024个可用OFDMA子信道中，共包含996个有效数据子信道的完整CFR数据，剩余子信道为控制子信道，无法获取信道读数。若您发现本项目具有实用价值并使用本数据集，请引用以下论文： @article{meneghello2023toward, author = {Meneghello, Francesca and Chen, Cheng and Cordeiro, Carlos and Restuccia, Francesco}, journal={IEEE Communications Magazine}, title = {{Toward Integrated Sensing and Communications in IEEE 802.11bf Wi-Fi Networks}}, year = {2023}, volume={}, number={}, pages={} }
