Design and Simulation of Indoor Positioning System Based on UWB

In this paper, Ultra wideband technology and the main features of indoor positioning technology is introduced, focusing on the design and establishment of a UWB-based indoor positioning system model, the transceiver structure of the system is determined, and then location algorithm, the receiver synchronization and channel estimation and other key technologies conducted in-depth study. On this basis, the detailed simulation of the entire system using Matlab/Simulink software platform is carried out. It has been proved by simulation results s that UWB indoor positioning system provides good positioning accuracy and better performance.
