It includes 4-channel signals, where each signal set consists of multiple frames. Each frame contains structures such as preamble, guard interval, data bits and trailing frame, and the data presents collected samples of the target under different azimuth angles. The signal data adopts a 3.5 GHz frequency deviation, and is particularly suitable for research in fields such as signal localization, angle estimation and wireless communications. The data was collected on-site at the University of Electronic Science and Technology of China (UESTC) in October 2024. The signal data is received via microstrip antennas and collected using software-defined radio (SDR) over-the-air technology, which ensures reliable and high-fidelity signal transmission during on-site acquisition. Each collected sample represents signal information acquisition of the target at different azimuth angles. The collected signals have undergone clipping and reconstruction optimization to support the development and testing of subsequent localization algorithms. The processing steps include efficient noise suppression, signal synchronization and data organization, etc., to ensure data quality and high consistency, making the dataset suitable for further signal analysis, localization research and algorithm validation. In particular, the optimized signal frame structure enables the dataset to better support the research and development of related technologies such as effective angle estimation and signal processing in practical applications. The release of this dataset will provide important data support for fields such as wireless localization technology, antenna optimization and wireless communication system research, promote the development of related technologies, and drive innovation in application scenarios such as wireless communication positioning.
