Abstract:
A system includes a three dimensional antenna and mobile devices that wirelessly communicate with the antenna. A phase of arrival and a phase difference of arrival are calculated, and a distance between the three dimensional antenna and the mobile device is calculated. A direction between the three dimensional antenna and the mobile device is calculated. The direction calculation includes an angular spread function of multipath scattering in the communication between the three dimensional antenna and the mobile device. The direction calculation further includes an estimation of a propagation delay and an angle in the communication between the three dimensional antenna and the mobile device.
