Abstract

The velocity estimation of UE (User Equipment) is very important for LTE (Long Term Evolution) system, in this paper a joint velocity estimation algorithm is proposed based on LTE system. In the proposed algorithm, the velocity is judged roughly by normalized standard deviation of the received power, and then channel auto-correlation function method is used in low or middle velocity condition and frequency offset estimation method is used in high velocity condition. The simulation results show the proposed algorithm has good estimation accuracy in low, middle or high velocity condition and has better performance than channel auto-correlation function method or frequency offset estimation method.
