Cellular Base Station Assisted Indoor Positioning

In this paper, first, two methods of positioning an indoor receiver with transferred global navigation satellite system signals from cellular base stations are proposed. Then, a technique of fusing the position results produced by the two methods through Kalman filter is introduced; thus, the positi...

Description
Summary:In this paper, first, two methods of positioning an indoor receiver with transferred global navigation satellite system signals from cellular base stations are proposed. Then, a technique of fusing the position results produced by the two methods through Kalman filter is introduced; thus, the positioning accuracy is improved. To mitigate the near-far problem generated by signals from base stations and satellites, a pulse shaping scheme and the strategy of assigning pulse patterns to base stations are investigated.
