Abstract：Through the precise positioning coordinates of RFID tag ,the user’s location is determined .The distance be-tween the user and the RFID reader is measured by PDOA algorithm ,because of the presence of measurement errors ,the gradient descent algorithm is used to get precise location .During the iterations ,Hesse matrix is used to get the optimal gra-dient descent step ,then to reduce the number of iterations .Simulation results show that the location algorithm can improve the speed and precision of the user location in the intelligent home system .
