It needs to use some physical layer measurement, such as signal to interference plus noise ratio(SINR), the user's mobile speed,etc.The de-modulation reference signal(DMRS）uplink channel information is used in orthogonal frequency division multiplexing(OFDM） system.The limit factor and modify factor can be used to reduce the influence of noise.And the calculating formula of auto correlation function(ACF) can be applied to different channel condition such as direct path or not.Simulation is carried out in different channel models and signal-to-noise ratio.Simulation results demonstrate that the proposed method can estimate the terminal moving speed stably and accurately.
