MSc thesis project proposal
Bluetooth Direction Finding
Project outside the universityIMEC-NL (Holst Centre), Eindhoven
Future versions of the Bluetooth specification will likely incorporate Angle-of-Arrival (AoA) and Angle-of-Departure (AoD) features which allow multi-antenna Bluetooth devices to determine the spatial location of another Bluetooth device. AoA and AoD will support high-accuracy location detection, potentially giving position accuracy to within tens of centimeters.
In the upcoming new Bluetooth standard, a device can make its direction available for a peer device by transmitting direction finding enabled packets. Using direction information from several transmitters and profile-level information giving their locations, a Bluetooth radio can calculate its own position.
The peer device, consisting of an RF switch and antenna array, switches antennas while transmitting. The receiver will captures IQ samples. The IQ samples can be used to calculate the phase difference in the radio signal received when switching between the various transmitt elements of the antenna array, which in turn can be used to estimate the angle of departure (AoD).
AssignmentIn this MSc. thesis project, the direction finding capabilities of future generation Bluetooth devices will be further investigated. Requirements and specifications based on the latest draft Bluetooth standard will be set for a multi-antenna AoA/AoD system. A prototype system will be build, and the performance will be evaluated.
The project can be broadly divided in three main phases:
- Literature overview The student gets acquainted with the state of the art AoA/AoD systems, the relevant section from the Bluetooth standard, and studies the expected accuracy from literature.
- Project plan Using the literate overview, the student proposes a prototype system to be study in detail including a time-line.
- Building AoA/AoD prototype, test the performance, and compare with the initial expectations.
- Thesis At the end of the project, the student is expected to produce a comprehensive project/MSc thesis report.
- The candidate is a Master's student in Electrical Engineering, with a high affinity for and solid knowledge of signal processing for communications and localization.
- The candidate likes to work with electronic hardware prototypes.
- Knowledge of Matlab or C is required.
- Good spoken and written English is a must.
- Expected project duration is 9 months.
