Embodiment 1

[0042] figure 1 The implementation process of the method for reducing interference signals in mobile communication provided by the first embodiment of the present invention is shown, and the details are as follows:

[0043] In step S101, the MIPI frequency among the parameters configured by the functional modules in the device is obtained.

[0044] Specifically, the devices described in the embodiments of the present invention may be communication terminals such as smartphones and tablet computers. Since the communication system in the device is used to ensure reliable data and voice, it is necessary to eliminate the interference signals caused by other functional modules in a timely manner.

[0045] At present, the sources of interference signals are mainly various functional modules in the device, including the display module, camera module, sensor module, and button module. If the channel is interfered, it may be caused by some of the functional modules.

[0046] In the e...

Embodiment 2

[0086] Take the display as an example, figure 2 It shows the implementation process of the method for reducing the interference signal of the display screen of mobile communication provided by the second embodiment of the present invention, and the details are as follows:

[0087] In step S201, the MIPI frequency and the number of MIPI lines in the configuration parameters of the display screen are read. After the circuit of each functional module in the device is determined, the MIPI frequency used by the display screen is stored as a constant.

[0088] In step S202, a first ratio for dividing the MIPI frequency is determined according to the number of MIPI lines on the display screen. The first ratio can be a value such as 1 / 4 or 1 / 12.

[0089] In step S203, the used frequency range is obtained according to the frequency band used in the device. In the present invention, it can generally be used for interference suppression on low-frequency frequency bands, such as GSM850...

Abstract

The invention provides a method and a device for reducing interference signals of mobile communication. The method comprises the following steps: acquiring an MIPI (Mobile Industry Processor Interface) frequency in parameters configured for a functional module in equipment; performing frequency division processing in a first preset ratio according to the acquired MIPI frequency to obtain a first fundamental frequency; performing frequency doubling processing on the first fundamental frequency to obtain a plurality of frequency-doubled frequency points; and searching for a channel of the frequency-doubled frequency points within a frequency range in use, and performing filter processing on the searched frequency-doubled frequency points in the channel. Through adoption of the method and the device, interference caused by the functional module in the equipment can be reduced effectively, and the interference signal processing timeliness is enhanced greatly while the labor force is saved.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method and a device for reducing interference signals of mobile communication. Background technique [0002] As the functions of mobile terminals such as mobile phones become more and more diversified, more and more functional modules are set in the mobile terminal, such as display screens, cameras, sensors, buttons and other functional modules. When setting each functional module, especially the interference source of the display module, it is necessary to strictly control the interference that its signal may bring to the communication system. [0003] At present, the processing of the interference signal of the communication radio frequency signal by the display screen is generally through the coupling sensitivity test method. That is, if some channels are interfered, the coupling sensitivity will deteriorate, and the interference source can be checked according to t...
