Indoor Positioning Technology Based on Multipath Effect Analysis

Exsiting indoor localization approaches have poor accuracy because of multipath effect. In this work, we utilize Perpendicular Intersection(PI) means, establishing the model o f multipath effect on signal propagation . The results show that multipath effect can be overcomed by PI and high accuracy is achieved.
