Detailed Description

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.

In the description that follows, embodiments of the invention are described with reference to steps and symbols of operations performed by one or more computers, unless otherwise indicated. It will thus be appreciated that those steps and operations, which are referred to herein several times as being computer-executed, include being manipulated by a computer processing unit in the form of electronic signals representing data in a structured form. This manipulation transforms the data or maintains it at locations in the computer's memory system, which may reconfigure or otherwise alter the computer's operation in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific details shown, since one skilled in the art will recognize that various steps and operations described below may be implemented in hardware.

Referring to fig. 1, fig. 1 is a flowchart of a radio frequency interference processing method in a preferred embodiment of the invention. The radio frequency interference processing method is applied to a terminal, and the terminal is provided with a radio frequency circuit. The radio frequency interference processing method comprises the following steps:

s101, when the strength of the received signal of the radio frequency circuit is detected to be smaller than a preset value, frequency range information of the received signal is obtained.

In this step, the terminal monitors the strength of the received signal of the rf circuit in real time. The preset values are data from a number of experiments. When the strength of the received signal is smaller than the preset value, the interference on the received signal of the radio frequency circuit is stronger, and when the strength of the received signal is larger than the preset value, the interference is weaker.

And S102, determining at least one first functional module according to the frequency band information, wherein the first functional module is a functional module which is currently running and generates interference on the received signal under the frequency band information.

The interference signal generated by each functional module only generates interference to the receiving signal of a specific frequency band. Therefore, when it is detected that the received signal is smaller than the preset value, at least one first functional module needs to be determined from the plurality of functional modules currently operating, and the first functional module generates radio frequency interference on the received signal under the current frequency band. The functional module refers to a display screen, a motor, a power supply, a fingerprint module, a loudspeaker and the like of the terminal.

S103, generating an anti-interference signal according to the at least one first functional module.

In this step, the interference signals of the first functional modules may be superimposed and then subjected to phase inversion processing, so as to obtain the interference-free signal.

And S104, performing anti-interference processing on the received signal by adopting the anti-interference signal.

In the step, the interference-resistant signal is superimposed on the received signal, so as to remove the interference signal therein.

Referring to fig. 2, fig. 2 is another flowchart of a radio frequency interference processing method in a preferred embodiment of the present invention, in the embodiment, the step includes the following steps:

s201, when the intensity of the received signal of the radio frequency circuit is detected to be smaller than a preset value, frequency range information of the received signal is obtained.

S202, at least one first functional module is confirmed according to the frequency band information, wherein the first functional module is a functional module which is currently running and generates interference on the received signal under the frequency band information.

The interference signal generated by each functional module only generates interference to the receiving signal of a specific frequency band. Therefore, when it is detected that the received signal is smaller than the preset value, at least one first functional module needs to be determined from the plurality of functional modules currently operating, and the first functional module generates radio frequency interference on the received signal under the current frequency band.

In this step, the step S202 includes:

s2021, acquiring a plurality of functional modules which are currently running.

S2022, determining at least one first functional module from the plurality of functional modules according to the frequency band information. The first functional module generates radio frequency interference to the received signal under the current frequency band.

S203, generating an anti-interference signal according to the at least one first functional module.

In some embodiments, this step S203 includes:

and acquiring the interference signal of each first functional module. The interference signal of each functional module is tested and stored in the memory of the terminal before the terminal leaves the factory.

And superposing and inverting the interference signals of the functional modules to obtain the anti-interference signals. The steps of superposition and inversion can be interchanged in this step.

In other embodiments, the step S203 includes:

s2031, determining at least one necessary function module and at least one unnecessary function module from the at least one first function module, where the necessary function module is a function module that must be called by an application running in the foreground, and the unnecessary function module is a function module that does not need to be called by an application running in the foreground.

S2032, acquiring the interference signal of the necessary functional module, and generating an anti-interference signal according to the interference signal. In this step, the interference-resistant signal can be obtained by performing an inversion process on the interference signal.

And S2033, closing the unnecessary functional module.

In other embodiments, the step S203 includes: acquiring an interference signal of each first functional module; filtering clutter signals of each interference signal according to the frequency band information to obtain target interference signals, wherein the clutter signals and the receiving signals are located in different frequency bands; and superposing and inverting the target interference signals to obtain anti-interference signals. Since the interference signal generated by each functional module is not a pure single-frequency band signal, and may have signals in other frequency bands, the signals in other frequency bands need to be filtered out to prevent a new interference signal from being introduced into the received signal.

And S204, performing anti-interference processing on the received signal by adopting the anti-interference signal.

In this step, in some embodiments, the interference signal is removed directly in this step by superimposing the interference rejection signal with the received signal.

In other embodiments, the strength of the interfering signal is also adjusted to facilitate better interference cancellation. After the step S2035, the step S204 includes:

s2041, acquiring the running state of the necessary functional module; for example, for a speaker, the operation state may be confirmed according to the volume level of the speaker, and the intensity of the interference signal generated at different volume levels is different. For the display screen, the operation state can be confirmed according to the brightness level of the display screen, the brightness is different, the voltage value is different, and therefore the intensity of the generated interference signal is different.

And S2042, acquiring an interference intensity value according to the running state. The interference strength value in each operating state is obtained through a plurality of tests in advance. For example, for a speaker, the volume x1-x2 is state one, the volume x2-x3 is state two, and the volume x3-x4 is state four, each corresponding to a disturbance intensity value.

S2043, setting the amplitude of the anti-interference signal according to the interference strength value to obtain the amplitude-adjusted anti-interference signal. And adjusting the amplitude of the anti-interference signal according to the interference intensity value so that the amplitude of the anti-interference signal is matched with the interference intensity value.

And S2044, performing anti-interference processing on the received signal by adopting the anti-interference signal with the adjusted amplitude.

The anti-interference processing is carried out on the received signal by adopting the anti-interference signal with the adjusted amplitude, so that the phenomenon that a new interference signal is introduced in the process of removing interference or the interference signal is not completely removed due to insufficient intensity of the anti-interference signal can be avoided; thereby having better anti-interference effect.

As can be seen from the above, in the radio frequency interference processing method provided in the embodiment of the present invention, when it is detected that the intensity of the received signal of the radio frequency circuit is smaller than a preset value, frequency band information of the received signal is obtained; confirming at least one first functional module according to the frequency band information, wherein the first functional module is a functional module which is currently running and generates interference on the received signal under the frequency band information; generating an anti-interference signal according to the at least one first functional module; and the anti-interference signal is adopted to perform anti-interference processing on the received signal, so that the beneficial effect of reducing the radio frequency interference of the received signal is achieved.
