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.

Abstract: A method and system detect directionality between two objects by measuring angles of signals incident on antenna arrays on at least one side to determine angle of incidence. The methods utilize Bluetooth Low Energy communications for both the control protocol and for providing updated information for deriving directionality. Directionality information is broadcast on selected BLE advertising or data channels, or broadcast using a hopping pattern over the BLE data channels, both at a specific interval duty cycle. If a hopping pattern is selected to transmit directionality information, then anchor information is simultaneously broadcast on the BLE advertising or data channels at a different, asynchronous duty cycle. In additional embodiments, signals incident on antenna arrays located on both target and tracking sides are used to determine angle of incidence, separate antennas are combined to form new antennas and antenna models are used to anticipate known antenna structure responses.

Abstract: Systems and apparatuses are provided for negating the degradation effects of fundamental coupling between at least two near field communication (NFC) enabled devices, at least one of which can receive frequency modulation (FM) signals. Due to the fundamental coupling, strong NFC signals can mix with blocking signals associated with a desired/tuned-to FM frequency causing degradation in FM receiver performance. By utilizing a notch filter at the front end of the FM receiver, the degradation in FM receiver performance caused by the fundamental coupling phenomenon can be avoided.
