Abstract: Indoor tracking technology based on Channel State Information received much attention in recent years.In order to realize real-time trajectory tracking by using existing commercial WiFi devices,this paper adopted indoor tracking system with one-transmitter and one-receiver,the multidimensional parameters calculated by Channel State information, including Time of Flight , Arrival of Angle, Doppler Frequency Shift and channel attenuation which were used to calculate the corresponding position information,and it used the environmental dynamic parameters contained in the static path to modify the positioning parameters, so as to achieve a high accurate tracking.Experiments show that the positioning accuracy is up to 0.65m by using with this method, which proves that this method can more accurately and effectively to realize the indoor positioning and tracking.
