摘要：A new algorithm is proposed for detecting and mitigating non-light of sight(NLOS) error in a time of arrival(TOA) based wireless positioning system. Received signal strength (RSS) is employed to detect whether a TOA value contains NLOS error and mitigate it. When the relationship between TOA and RSS in light of sight (LOS) situation is known, a possibility of NLOS can be calculated using the TOA & RSS measurement results which are provided by a base station. Then the TOA measurement results can be trimmed using the possibility mentioned above. Finally, the algorithm is implemented in a wireless positioning system. Experiment results show that the algorithm can mitigate the effect of NLOS without increasing times of measurements.
