Abstract

The invention discloses a clock frequency adjusting system, a clock frequency adjusting method and a mobile terminal, belonging to the technical field of mobile communication. The system comprises a frequency monitoring unit, a judging unit and an adjusting unit, wherein the judging unit is connected to the frequency monitoring unit; and the adjusting unit is connected to the judging unit. The method comprises the following steps: S1, monitoring and obtaining a receiving frequency of a frequency point used by a currently received signal of the mobile terminal; S2, judging whether the frequency point used by the received signal of the mobile terminal is a multiplied-frequency point of a clock frequency currently used by a storage of the mobile terminal or not, and returning to the step S1 if the frequency point used by the received signal is not the multiplied-frequency point of the clock frequency currently used; and S3, selecting one preset clock frequency as the current clock frequency of the storage, and then, returning to the step S1. The technical scheme provided by the invention has the benefits that: the performance of a fixed interfered channel of the mobile terminal is improved; the problem that the radio-frequency performance of the mobile terminal is influenced due to wireless sensitivity deterioration can be avoided; furthermore, protocol requirements can be satisfied; and the clock frequency adjusting system, the clock frequency adjusting method and the mobile terminal disclosed by the invention are relatively simple to realize and relatively low in realization cost.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a clock frequency adjustment system and method and a mobile terminal. Background technique [0002] In the prior art, the ability of a mobile terminal to receive signals is closely related to its wireless sensitivity. Improving the wireless sensitivity of the mobile terminal can enable the mobile terminal to have a stronger ability to capture weak signals. In this way, as the transmission distance increases, the received signal becomes weaker, and high-sensitivity wireless products can still receive data, maintain a stable connection, and greatly increase the transmission distance. However, in the prior art, the working frequency of the memory of the mobile terminal may interfere with the wireless sensitivity of the received signal, thereby affecting the radio frequency performance of the mobile terminal. Contents of the invention [0003] According to th...
