Claim Text:
1. A method for testing a moving speed of a terminal, wherein the method comprises: receiving, by a receiving end, a signal comprising a pilot sequence transmitted by a transmitting end; determining, by the receiving end, a time-domain channel estimation value corresponding to each pilot symbol being transmitted, in the pilot sequence according to a known pilot sequence and the signal comprising the pilot sequence and selecting a delay path according to the time-domain channel estimation values; and determining, by the receiving end, the moving speed of the terminal according to the delay path selected in a preset length of time; wherein before determining, by the receiving end, the time-domain channel estimation value corresponding to each pilot symbol being transmitted, in the pilot sequence according to the known pilot sequence and the signal comprising the pilot sequence and selecting the delay path according to the time-domain channel estimation values, the method further comprises: determining, by the receiving end, noise power when the signal comprising the pilot sequence is received, and determining a signal to noise ratio corresponding to the noise power according to the noise power; and determining that the signal to noise ratio is above a first preset threshold.
