Abstract :
This letter presents a novel non-line-of-sight (NLOS) localization scheme based on the concept of virtual reference device. The position of virtual reference device for each NLOS path can be determined if the initial mobile device position can be estimated or when the mobile device transits from LOS to NLOS region. With the position of virtual reference devices, the subsequent localization of mobile device requires only one signal path. Simulation and experiment conducted in indoor multipath environment show that the performance of our proposed localization scheme surpasses the existing localization schemes by a significant margin at all simulated and measured locations.
