Abstract:
This disclosure relates to techniques for performing ranging wireless communication in a secure manner. A first wireless device may receive a plurality of independent sequences from a second wireless device. The first wireless device may perform a combined channel estimate using the sequences. The first wireless device may estimate the distance (or angle/direction, among various possibilities) between the two devices based on the combined channel estimate.
