Abstract

The application discloses a frequency compensation method, a mobile terminal and storage equipment. The compensation method includes the following steps: the mobile terminal acquires the own movementspeed; the mobile terminal accesses a base station and acquires a communication carrier frequency of the base station; the mobile terminal calculates a Doppler frequency according to the movement speed and the communication carrier frequency; and the mobile terminal performs frequency compensation on transmitted and received signals according to a pre-stored oscillation frequency and the Doppler frequency. By adopting the method, the problem of Doppler effect in high-speed mobile communication of the mobile terminal can be solved.

Description

technical field [0001] The present application relates to the field of frequency compensation, in particular to a frequency compensation method, a mobile terminal and a storage device. Background technique [0002] With the development of high-speed railways, the speed of trains is getting higher and higher. Due to the influence of the Doppler effect, the communication performance of mobile phones will be reduced or even interrupted when using mobile phones on high-speed trains. The traditional receiving and transmitting local oscillation frequency is directly controlled by the mobile phone terminal processor according to the channel to be received and transmitted, which can meet the needs of the mobile terminal to send and receive signal channels when it is static. However, it cannot meet the needs of the mobile terminal to send and receive signal channels when moving at high speed. [0003] Due to the Doppler effect, the high-speed mobile terminal will cause the mixed sig...
