ST_URA8_Dataset_part_3

This is a dataset for Bluetooth 5.1 DoA applications with URA8 antenna arrays. It was conceived as a starting point for developing and validating DoA algorithms for real-life scenarios. Unlike other datasets, it contains Bluetooth signals with not only varying intensity of additive white Gaussian noise, but also coherent interfering signals with random DoA coordinates. The dataset is divided into two branches, one consisting of pure sinusoidal tones and the second comprised of baseband Bluetooth signals. The Python code which generated this dataset is included. Therefore, the dataset can be expanded and also modified to suit other types of signals and simulate other types of antenna arrays. Please note that this is only the first part of the dataset. The dataset is comprised of four parts, and you need to download all of them in order to recreate the entire directory structure.
