| titleOfInvention | Method for estimating and compensating for NLOS bias in time difference of arrival estimation |
| abstract | Devices, systems, and methods are provided for compensating for non-line-of-sight ("NLOS") bias in time difference of arrival ("TDOA") estimates between a first anchor point and a second anchor point in a network having an obstruction in the line-of-sight between the first anchor point and the second anchor point. The system and method include transmitting a first data packet from a first anchor point; the second anchor point indirectly receives the first data packet and then sends a second data packet; the first anchor point indirectly receives the second data packet; and the mobile node receives the first data packet and the second data packet. A true time-of-flight of the first or second packet between the first anchor and the second anchor and a deviation in time-of-flight of the first or second packet between the first anchor and the second anchor are estimated. The time difference of arrival at the mobile device between the direct path and the indirect path is further estimated, and the NLOS bias in the time difference of arrival estimated at the mobile device is corrected. |
