Dataset of Bluetooth Low Energy IQ samples for Angle of Arrival determination

One significant challenge in research is to collect a large amount of data and learn the underlying relationship between the input and the output variables. This data, collected in a laboratory setting, is intended to approximate real-world industrial scenarios. The samples were collected using a Texas Instruments (TI) BOOST-XL-AOA antenna array and the Ground Truth (GT) position of the tag was tracked and logged by a motion capture system with millimetre accuracy. This position was used to calculate the angle between the tag and the antenna array. The collected samples and the process of generating GT labels were validated using the TI phase difference of arrival (PDoA) implementation on the data, yielding a mean absolute error (MAE) at one of the heights without obstacles of 25.71 degrees.
