IQ data for a given TX-RX beam index pair for link-level analysis in the 60 GHz band

In this dataset, based on a beam sweeping experiment in the 60 GHz band in an indoor environment, we provide the acquired IQ data samples (containing the announced TX antenna weighting vectors (AWV) index as information) for the given RX AWV index, location, and carrier frequency. We also include the information obtained after processing the PPDU in IQ data.In the experiment, we use one fixed SDR and a mobile SDR, developed at the University of South Carolina for the AERPAW platform, by using Sivers EVK06002 and RFSoC2x2. The companion computer (CC) of the mobile SDR first sets the TX AWV index. It then generates a custom OFDM-based PPDU, where the data bits indicate the utilized TX AWV index. The PPDU length is 1280 complex samples (i.e., 4 OFDM symbols (synchronization, channel estimation, header, and data symbols) - 1.2 GHz bandwidth). The CC transmits the PPDU along with a test waveform, where the test waveform consists of a ramp waveform (50 samples), zero samples (25 samples), a tone (50 samples), and zero samples (25 samples) for evaluating potential impairments. After the transmission, the CC increases the TX AWV index and repeats the aforementioned announcement procedure. In our experiment, the CC completes the announcements of 64 TX AWV indices in less than 2 sec. The corresponding CC of the fixed SDR first sets the RX AWV index. It waits for 2 sec. It then pulls the corresponding IQ samples (1580 samples). The dataset has these IQ samples. The data is collected when the link distance between the SDRs is reduced from 9.75 m to 2.44 m with a spacing of 12" (i.e., 25 locations). We use the default set of 64 AWV for 60.48 GHz, provided by Sivers, sweeping the azimuth between -45 and 45 degrees, uniformly. We collect the data for both 60.48 and 65.34 GHz.By decoding the PPDU (If the decoding is successful), we provide the detected TX AWV index, SNR, channel frequency response, and channel impulse response. More physical layer parameters can be obtained by processing the provided IQ data further.SDR source codes: https://github.com/alphansahin/mmWaveSDR

本数据集基于室内环境下60 GHz频段内的波束扫描实验，提供了所获取的IQ数据样本（包含已宣布的TX天线加权向量（AWV）索引作为信息），对应于指定的RX AWV索引、位置和载波频率。此外，我们还包含了从IQ数据中处理PPDU后获得的信息。在实验中，我们采用了一台固定的软件定义无线电（SDR）和一台移动SDR，由南卡罗来纳大学为AERPAW平台开发，利用Sivers EVK06002和RFSoC2x2。移动SDR的伴随计算机（CC）首先设置TX AWV索引，随后生成基于OFDM的自定义PPDU，其中数据位表示所使用的TX AWV索引。PPDU长度为1280个复数样本（即4个OFDM符号（同步、信道估计、头部和数据符号）- 1.2 GHz带宽）。CC将PPDU与测试波形一同发送，测试波形由一个斜坡波形（50个样本）、零样本（25个样本）、一个纯音（50个样本）和零样本（25个样本）组成，用于评估潜在的损害。传输完成后，CC增加TX AWV索引并重复上述宣布程序。在我们的实验中，CC在不到2秒内完成了64个TX AWV索引的宣布。固定SDR的对应CC首先设置RX AWV索引，等待2秒后，提取相应的IQ样本（1580个样本）。数据集包含这些IQ样本。数据收集时，SDR之间的链路距离从9.75米减少到2.44米，间隔为12英寸（即25个位置）。我们使用Sivers提供的默认64个AWV集，针对60.48 GHz频段，以-45至45度之间的方位角均匀扫描。我们收集了60.48和65.34 GHz频段的数据。通过解码PPDU（如果解码成功），我们提供了检测到的TX AWV索引、信噪比、信道频率响应和信道冲激响应。通过进一步处理提供的IQ数据，还可以获得更多物理层参数。SDR源代码：https://github.com/alphansahin/mmWaveSDR
