FIRST ARRIVAL PATH BASED MULTIPATH MITIGATION FOR ANGLE OF ARRIVAL ESTIMATION

摘要

A system and method are disclosed that may provide an accurate estimate of the angle of arrival (AoA) of a wireless signal received by a device. The received wireless signal may include a plurality of signal components (702) associated with a number of different arrival paths. The device may generate a weighted signal, including a plurality of weighted signal components, by multiplying the plurality of signal components of the received wireless signal with a set of weighting values (704). The device may identify one or more of the weighted signal components associated with a first arrival path to the device (706), determine phase information of the one or more identified weighted signal components (708), and then determine the angle of arrival based, at least in part, on the determined phase information (710).
