Embodiment Construction
[0012] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, which should not be construed as a limitation on the technical solution.
[0013] 1. The relationship between the frequency offset and the transmission frequency, movement speed and direction of movement is determined by the Doppler effect, as shown in the formula
[0014] f d = f C v · cos ( α ) - - - ( 1 )
[0015] Among them, α is the angle between the terminal moving direction and the signal propagation direction, v is the terminal moving speed, C is the electromagnetic wave propagation speed, and f is the carrier frequency;
[0016] 2. Determine the frequency offset relationship of the mobile terminal relative to two base statio...
