Abstract
Techniques by a wireless to estimate the position of a remote device are disclosed. A main receiver of the wireless device may determine multiple first phase values of the RF signal received through a first antenna during multiple time intervals. An auxiliary receiver may determine multiple second phase values of the RF signal received through an array of auxiliary antennas during the multiple time intervals. Each of the second phase value may correspond to the RF signal received through one antenna of the array during one of the time interval. The wireless device may determine an oscillator offset between a local oscillator of the main transceiver and a local oscillator of the auxiliary receiver. The wireless device may estimate an angle of arrival (AoA) of the RF signal or a distance based on the multiple first phase values and the multiple second values by compensating for the oscillator phase offset.
