摘要

The accuracy of localization is exceedingly important since high accuracy positioning information can benefit location-based services. Non-line-of-sight (NLOS) errors are one of the most important factors affecting the accuracy of localization. To improve the positioning accuracy, it is necessary to reduce the impact of the NLOS errors. This letter proposes a novel semidefinite programming (SDP) o...
