Abstract

Received signal strength indication method enables flexible positioning without additional hardware installation and modification from communication resources. The expectation value of distance is changed due to the shadow fading. The effects of shadow fading in indoor RSSI ranging and convergence with pedestrian dead reckoning by using Extended Kalman Filter are presented. The fusion of pedestrian dead reckoning and RSSI ranging simulation shows that the compensation Shadow Fading effect has slightly less errors.
