发明名称 ROUND TRIP TIME ACCURACY IMPROVEMENT IN VARIED CHANNEL ENVIRONMENTS
摘要 Methods, systems, and devices are described that provide for wireless ranging. The methods, systems, and/or devices may include tools and techniques that provide for determining a range based on a TOD and a TOA that is adjusted based on a mean FAC. A probe may be transmitted from a transmitter to a receiver. The transmitter may receive a response, from the receiver. A strongest path within the response may be identified. A threshold may be determined. A plurality of FAC values may be identified, which exceed the threshold and precede the strongest path within the response. After the plurality of FAC values are identified, a mean FAC may be determined based at least in part on the plurality of FAC values. A TOA of the response may be adjusted based on the mean FAC. A range to the receiver may be determined based on a TOD and the adjusted TOA.
