Problems solved by technology

However, after the hardware design of mobile communication terminals, such as mobile phones, is completed, once there is radio frequency interference (217Hz and its harmonics) noise in 2G (Global System of Mobile Communication) mode or radio frequency interference in 3G mode ( 200Hz and its harmonics) noise, many people will be at a loss and spend a lot of time making major modifications to the hardware, and sometimes modifying the hardware cannot completely eliminate radio frequency interference, which brings difficulties to the design and development of mobile communication terminals

Embodiment Construction

[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] figure 1 It is a schematic flowchart of an embodiment of a method for eliminating radio frequency noise of a mobile terminal in the present invention.

[0041] refer to figure 1 , the present invention eliminates the method for mobile terminal radio frequency noise to comprise the following steps:

[0042] Step S01, collecting data in the uplink voice channel, and performing time-frequency conversion on it;

[0043] After the mobile terminal establishes a voice call, the radio frequency interference is mainly introduced through the MIC (microphone) in the uplink voice path. Therefore, before the data in the uplink voice channel enters the Side_Tone sound me...

Abstract

Disclosed is a method and an apparatus for eliminating radio frequency noise of a mobile terminal. The method comprises the following steps: collecting data in an uplink voice channel, and performing time-frequency transformation on the data; determining whether radio frequency noise exists in the data of the uplink voice channel after the time-frequency transformation; if yes, performing noise elimination processing on the data in the uplink voice channel in a frequency domain. In the present invention, data is collected from the uplink voice channel, and noise elimination processing is performed when it is obtained through analysis that radio frequency noise exists in the data, so that radio frequency interference can be effectively avoided, and the quality of voice calls is ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for eliminating radio frequency noise of a mobile terminal. Background technique [0002] With the continuous development of mobile communication technology and the improvement of the quality of life, users not only put forward new requirements for the functions of mobile communication terminals, but also pay more and more attention to the audio quality of mobile communication terminals, which affects the user satisfaction of mobile communication terminals. And hearing comfort puts forward higher and higher requirements. [0003] For a mobile communication terminal, noise may be generated in each link of the voice uplink and downlink channels, and these various noises will directly affect the call quality of the user. Part of the noise, such as background noise and other steady-state noise, can be eliminated by commonly used noise reduction algorithms; part of the...
