Ultra Dense Indoor MaMIMO CSI Dataset
收藏资源简介:
This dataset contains thousands of Channel State Information (CSI) samples collected using the 64-antenna KU Leuven Massive MIMO testbed. The measurements focused on four different antenna array topologies; URA LoS, URA NLoS, ULA LoS and, DIS LoS. The users channel is collected using CNC-tables, resulting in a dataset where all samples are provided with a very accurate spatial label. The user position is sweeped across a 9 squared meter area, halting every 5 millimeter, resulting in a dataset size of 252,004 samples for each measured topology. To the best of our knowledge, this is the biggest open dataset containing measured MaMIMO CSI samples. The dataset can, for example, be used to visualise precoders and validate positioning algorithms.
本数据集包含利用64天线鲁汶大学(KU Leuven)大规模多输入多输出(Massive MIMO)测试平台采集的数千个信道状态信息(Channel State Information, CSI)样本。本次测量聚焦于四种不同的天线阵列拓扑:URA LoS、URA NLoS、ULA LoS与DIS LoS。研究采用CNC工作台采集用户信道数据,使得所有样本均附带高精度空间标注。用户位置在9平方米的区域内逐点扫描,每5毫米暂停一次,因此每种被测拓扑对应252004个样本。据我们所知,这是目前公开的规模最大的实测大规模MIMO CSI样本数据集。本数据集可用于可视化预编码器以及验证定位算法。
