Abstract
A system for detecting angle-of-arrival (AoA) includes a first device and at least one second device. The first device transmits a Bluetooth (BT) packet, and the second device receives the BT packet and determines an AoA of the BT packet. The second device includes a first radio-frequency (RF) antenna to receive a first RF signal and a second RF antenna to receive a second RF signal. The second device also includes a first BT core and a second BT-core and a processing circuit. The first BT core is coupled to the first RF antenna and is used to generate a first signal based on the first RF signal. The second BT core is coupled to the second RF antenna and generates a second signal based on the second RF signal. The processing circuit measures a phase difference between the first signal and the second signal and determines the AoA based on the phase difference.
