CSI Dataset dichasus-dcxx: Institute hallway with known 3D model, distributed antennas

Dataset containing channel state information (CSI) alongside ground truth data (position tags, timestamps) of a massive MIMO-OFDM system measured with the DICHASUS channel sounder. Measurement parameters and machine-readable file format descriptions are provided in a JSON file (spec.json). Two separate antenna arrays with 64 antennas in total observe a transmitter in a hallway with known 3D model, ideal for raytracing experiments.本数据集收录了采用DICHASUS信道探测仪（channel sounder）实测得到的大规模多输入多输出-正交频分复用（massive MIMO-OFDM）系统的信道状态信息（Channel State Information, CSI），以及对应的真实标注数据（位置标签、时间戳）。相关测量参数与机器可读文件格式说明已在JSON格式文件spec.json中给出。 两套独立天线阵列（总计64根天线）对位于带有已知三维模型的走廊内的发射机进行观测，该场景非常适合用于射线追踪（raytracing）实验。
