Abstract

The embodiment of the invention provides a frequency deviation processing method and a system and a repeater; the frequency deviation processing method comprises the following steps: a navigation signal is received, and the current moving position and the moving speed of a mobile station can be obtained according to the navigation signal; frequency deviation value of an interactive signal betweena base station and the mobile station is obtained according to the current moving position, moving speed and the corresponding relation of the stored moving route in-line position and a serving base station position; frequency deviation correction treatment is carried out to the interactive signal between the base station and the mobile station according to the frequency deviation value. In the embodiment of the invention, the repeater on mobile equipment is adopted to calculate the frequency deviation value of the interactive signal between the base station and the mobile station, so as to eliminate the effect of doppler effect on the interactive signal between the base station and the mobile station according to the navigation signal according to the frequency deviation value and improve the communication quality.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a frequency offset processing method and system, and a repeater. Background technique [0002] With the continuous development of mobile communication technology, railway coverage technology has also developed rapidly. GSM railway coverage can provide communication services for mobile stations on the train. With the continuous development of the railway industry, high-speed trains have gradually replaced traditional trains. The high-speed train runs at a high speed. Therefore, the mobile station inside the high-speed train communicates and interacts with the base station outside the high-speed train, which will cause the Doppler shift effect to occur and cause the frequency of the signal to shift. [0003] In the prior art, in order to overcome the signal frequency deviation caused by the Doppler effect, after the base station receives the signal s...
