Abstract: Embodiments of the present disclosure relate to device, method, apparatus and computer readable storage medium of relative phase determination for frequency drift compensation. The method comprises obtaining, at a first device and from a second device, a first reference signal associated with a reference antenna in a first time period and a second reference signal associated with the reference antenna in a second time period after the first time period; and determining a phase relationship between the reference antenna and at least one target antenna at least based on the first reference signal and the second reference signal, the at least one target antenna and the reference antenna being located in a same antenna array. In this way, the compensation of the frequency drift can be achieved based on the determination of the relative phase, which critical for the localization accuracy and stability in a high-accuracy BLE AoA/AoD localization solution.

Abstract: An access system for a vehicle is provided. The access system includes antennas and an access module. The antennas are configured to each receive a signal transmitted from a portable access device to the vehicle. The signal is transmitted on a 2.4 gigahertz frequency. The access module is configured to: downconvert the received signal to generate an in-phase signal and a quadrature phase signal; perform carrier phase based ranging including implementing a music algorithm to (i) determine a distance between the portable access device and the vehicle, and (ii) determine angles of arrival of the received signal as received at the antennas; determine a location of the portable access device relative to the vehicle based on the distance and the angles of arrival; and permit access to the vehicle based on the location.

Abstract: An access system for a vehicle is provided and includes antennas and an access module. The antennas are configured to each receive a signal transmitted from a portable access device to the vehicle. One of the antennas is a circular polarized antenna. The access module is configured to: downconvert the received signal to generate an in-phase signal and a quadrature phase signal; execute a music algorithm to determine angles of arrival of the received signal as received at the antennas; determine a distance between the portable access device and the vehicle based on the angles of arrival; and permit access to the vehicle based on the distance.

Abstract: An electronic device may use information about the location of nearby devices to make sharing with those devices more intuitive for a user. The electronic device may include control circuitry, wireless circuitry including first and second antennas, and motion sensor circuitry. The control circuitry may determine the location of a nearby electronic device by calculating the angle of arrival of signals that are transmitted by the nearby electronic device. To obtain a complete, unambiguous angle of arrival solution, the electronic device may be moved into different positions during angle of arrival measurement operations. At each position, the control circuitry may calculate a phase difference associated with the received signals. Motion sensor circuitry may gather motion data as the electronic device is moved into the different positions. The control circuitry may use the received antenna signals and the motion data to determine the complete angle of arrival solution.

Abstract: Disclosed are systems, devices and methods for determining an angle of arrival (AoA) of a signal transmitted between devices. Particular implementations enable obtaining measurements of AoA from signals that are not pure tone signals. In one aspect, a reference signal may emulate one or more aspects of a packet signal as transmitted by a transmitter. An AoA of the packet signal may be determined based, at least in part, on the packet signal and the reference signal.

Abstract: A system for multi-ship geolocation of a signal emitter of interest uses differential GPS (DGPS) to determine the relative positions of two or more receivers in order to determine baseline vectors between them. The geolocation of the signal emitter is then determined as a function of the baseline vectors. The use of DGPS allows for more efficient and useful geometries between the receivers as two receivers can both be in a mainlobe of an emitted signal and still provide increased geolocation accuracy.
