uwb2

This directory contains the data acquired from UWB system 2. The files are in .csv format and each row in the file corresponds to a received UWB packet. Each packet consists of 50 complex Channel Impulse Response (CIR) values which have been exchanged between pairs of UWB modules in a 5-device configuration. This dataset also contains other information such as the activity being performed, timestamp in milliseconds, experiment number, person id, room id, first path power and received power levels, ground truth XY coordinates of the person in the room, among others. More details on the UWB system and structure of the UWB data are available in the "Methods" and "Experiment Directory" sections of the Data Descriptor, respectively.

本目录包含超宽带（UWB）系统2采集得到的实验数据集。所有文件均采用逗号分隔值（CSV）格式，文件内每一行对应一条接收到的UWB数据包。每个数据包包含50个复信道冲激响应（Channel Impulse Response, CIR）数值，这些数值由5设备配置下的成对UWB模块交互产生。本数据集还涵盖其他多项信息，包括当前执行的活动、毫秒级时间戳、实验编号、受试者ID、房间编号、首径功率与接收功率电平、受试者在房间内的真值XY坐标等。有关UWB系统及UWB数据结构的更多细节，可分别参阅数据说明文档的“方法（Methods）”与“实验目录（Experiment Directory）”章节。
