Abstract

The embodiment of the invention discloses a method for improving radio frequency offset of a mobile terminal and the mobile terminal. The method for improving the radio frequency offset of the mobile terminal comprises the steps of obtaining radio frequency offset values of communication channels; carrying out data processing on the radio frequency offset values corresponding to a plurality of sample points obtained in a preset processing cycle to obtain data offset values; comparing the data offset values with a preset threshold; and carrying out frequency compensation on the communication channels when the data frequency offset values are greater than the preset threshold. According to the technical scheme of the method and the mobile terminal, the radio frequency offset of the mobile terminal can be improved, and the communication stability of the mobile terminal can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for improving radio frequency deviation of a mobile terminal and the mobile terminal. Background technique [0002] In recent years, with the rapid development of communication technology, more and more functions have been integrated into mobile terminals, and mobile terminals complete network interaction and information exchange by communicating with base stations. Because the base station sends and receives high-frequency signals, it is necessary to use radio frequency technology to modulate the signal of the mobile terminal to a high-frequency signal with the same frequency as the base station signal to realize the communication between the mobile terminal and the base station. [0003] In the prior art, manufacturers of mobile terminals perform AFC (Automatic Frequency Control, automatic frequency control) calibration on the mobile terminals before leaving the...
