NON-LINE-OF-SIGHT (NLOS) AND LINE-OF-SIGHT (LOS) CLASSIFICATION TECHNIQUES FOR INDOOR RANGING |
摘要 |
Techniques for use in determining a position of a mobile device are provided in which a range estimate can be classified as a line-of-sight (LOS) range estimate or a non-line-of-sight (NLOS) range estimate and the range estimate and classification can be used to determine the position of the mobile device. A method according to these techniques includes determining channel impulse response (CIR) information based on at least one measurement of signals exchanged between the mobile device and another wireless device; classifying a range estimate representing an estimated distance between the mobile device and the other wireless device as a line-of-sight (LOS) range estimate or a non-line-of-sight (NLOS) range estimate based at least in part on the CIR information; and using the range estimate and the classification of the range estimate to determine the position of the mobile device. |

1. A method for use in determining a position of a mobile device, the method comprising, at a computing platform:
determining channel impulse response (CIR) information based on at least one measurement of signals exchanged between the mobile device and another wireless device; classifying a range estimate representing an estimated distance between the mobile device and the other wireless device as a line-of-sight (LOS) range estimate or a non-line-of-sight (NLOS) range estimate based at least in part on the CIR information; and using the range estimate and the classification of the range estimate to determine the position of the mobile device. |
