Location estimation based on adjusted distance values for a wireless device

摘要

Embodiments of techniques and systems for distance and location estimation in wireless systems are described. In embodiments, a wireless device may receive wireless signals from reference points in a spatial arrangement. The wireless device may identify a closest reference point and generate arrangement-based distance values for each of the reference points based on a propagation model. The wireless device may adjust the propagation model based on the received wireless signals and the arrangement-based distance values, and may generate adjusted distance values using the adjusted propagation model. The wireless device may use the adjusted distance values and the spatial arrangement to estimate the location of the wireless device. Other embodiments may be described and claimed.

主权项

1. At least one non-transitory machine-accessible medium comprising instructions stored thereon that are configured to cause a wireless device, in response to execution of the instructions by the wireless device, to:
receive, by the wireless device, a plurality of wireless signals transmitted from a corresponding plurality of reference points in a spatial arrangement; identify a reference point of the plurality of reference points that is closest to the wireless device based on the plurality of received wireless signals and a propagation model; generate, for each of the plurality of reference points, an arrangement-based distance value representative of the distance between the wireless device and the reference point based at least in part on the closest reference point and the spatial arrangement; adjust the propagation model based at least in part on one or more of the plurality of received wireless signals and one or more of the arrangement-based distance values; generate, for each of the plurality of reference points, an adjusted distance value representative of the distance between the reference point and the wireless device based at least in part on the corresponding received wireless signal and the adjusted propagation model; and estimate the location of the wireless device based on the spatial arrangement and the adjusted distance values.
