Abstract
Provided are a method and device for testing the moving speed of a terminal, which are used for testing the moving speed of a terminal according to the pilot and noise power, thereby improving measurement accuracy. The method comprises: a receiving end receiving a signal which comprises a pilot sequence and is sent by a sending end; according to the known pilot sequence and the signal comprising the pilot sequence, the receiving end determining an estimated value of a time-domain channel corresponding to each pilot symbol of the pilot sequence in a transmission process, and selecting a time-delay path according to the estimated value of the time-domain channel; and according to the time-delay path selected in a preset time length, the receiving end determining the moving speed of a terminal.
