Abstract :
The accuracy of RFID real time location system depends on the accuracy of time difference of arrival measurement, for the problem of high precision measurement of the time difference of arrival in RFID real time location system, this paper analyzes the time difference of arrival measurement error. In the RFID real time location system, using link forwarding technology in order to avoid time integration errors which will affect the position accuracy; using phase interpolation method to obtain precise measurement of time difference of arrival, in order to achieve the purpose of improving position accuracy.
