Abstract
In one embodiment, an apparatus includes a processor for processing a plurality of radio frequency chains at a wireless device in a block based modulation environment, recording subcarrier phases and differences between the subcarrier phases, and using the subcarrier phase differences to construct a feature vector for use in angle of arrival calculated positioning of a mobile device, and memory for storing the subcarrier phases and the feature vector.
