Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

In one embodiment, as shown in fig. 1, a method for reducing noise is provided, and this embodiment is illustrated by applying the method to a terminal, and it is to be understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:

s110, acquiring a noise intensity signal of a target module in the communication equipment.

The communication device may be understood as a terminal device having a communication function, for example: smart phones, interphones, smart watches, and the like. A destination module may be understood as a component of a communication device that is capable of generating a Data (Data) signal and a Clock (Clock) signal. The target module may include at least one of a Liquid Crystal Display (LCD) module, a Camera (CAM) module, a memory module, and a dc converter module. The noise strength signal can be understood as a signal representing the interference strength of the noise in the target module on the radio frequency signal. The preset threshold may be understood as a preset noise threshold, or as the case may be, the embodiment is not particularly limited.

In order to reduce noise, firstly, a noise intensity signal of a target module in the communication device needs to be acquired, and the size of the noise intensity signal is judged, so that corresponding measures are taken to reduce noise when the noise intensity signal is greater than or equal to a preset threshold value subsequently.

And S120, when the noise intensity signal is greater than or equal to the preset threshold value, adjusting the working frequency of the target module through a clock frequency adjusting unit corresponding to the target module to obtain the corresponding target working frequency.

The clock frequency adjusting unit may be understood as a device configured in a radio frequency transceiver chip in the communication device for adjusting the clock frequency. The radio frequency transceiver chip can be understood as an electronic component which converts radio signal communication into a certain radio signal waveform and sends out the radio signal waveform through antenna resonance, and the radio frequency transceiver chip mainly plays a role in realizing signal transmission and signal reception. The target operating frequency may be understood as the operating frequency of the target module at which the noise strength signal does not interfere with the reception of other signals.

Because a clock signal and a data signal of a target module have certain high-frequency spectrum components in the communication process, the high-frequency spectrum components fall in the channel range of a received signal in a communication system, so that a noise signal is generated, and the noise signal can cause the receiving sensitivity of the signal of the frequency band to be reduced, thereby causing the receiving performance of the communication system to be poor. Therefore, when the noise intensity signal is greater than or equal to the preset threshold, it is indicated that the noise intensity signal interferes with the reception of the signal, the clock frequency adjusting unit corresponding to the target module adjusts the working frequency of the target module, and specifically, the clock frequency adjusting unit can adjust the working frequency of the target module to be higher or lower until the working frequency is adjusted to be a proper working frequency, so that the corresponding target working frequency can be obtained, the high-frequency spectrum component cannot fall into the adjusted target working frequency, and adverse effects on the reception of the signal in the target working frequency are avoided.

It should be noted that: after determining the target operating frequency, it is not necessary to determine whether the noise intensity signal at that time is less than a preset threshold.

According to the method for reducing the noise, the noise intensity signal of the target module in the communication device is obtained, when the noise intensity signal is greater than or equal to the preset threshold value, the clock frequency adjusting unit corresponding to the target module adjusts the working frequency of the target module to obtain the corresponding target working frequency, and the clock frequency adjusting unit automatically adjusts the working frequency of the target module, so that the noise can be reduced, and the clock signal and the data signal of the target module in the communication device are prevented from influencing the receiving performance of the communication system.

In this embodiment, optionally, the preset threshold may be set and adjusted according to measured data of the rf antenna, and the finally determined preset threshold is written into an NV RAM controlled by a baseband chip of the communication device as a parameter of a Non-Volatile Random Access Memory (NV RAM).

In the embodiment, the mode of determining the preset threshold is more flexible, the threshold does not need to be estimated through complex calculation, the working efficiency can be improved, and the time can be saved.

Fig. 2 is a schematic flow chart of another method for reducing noise according to an embodiment of the present disclosure. The embodiment is further expanded and optimized on the basis of the embodiment. Wherein, one possible implementation manner of S120 is as follows:

and S1201, when the noise intensity signal is greater than or equal to the preset threshold, controlling the target module to adjust the corresponding working frequency for multiple times within a preset time period through the corresponding clock control signal in the clock frequency adjusting unit, so as to obtain the corresponding relation between the noise intensity signal and the working frequency.

The preset time period may be preset, or may be determined according to a specific situation, and the embodiment is not particularly limited.

When the noise intensity signal is greater than or equal to the preset threshold, the target module can be controlled to adjust the working frequency of the target module for multiple times within the preset time period through the corresponding clock control signal in the clock frequency adjusting unit, specifically, the working frequency can be divided into multiple frequency band ranges in advance, linear scanning is performed in each frequency band range respectively, for example, 1MHz is taken as a step, linear scanning is performed continuously, and finally, the corresponding relationship between multiple groups of related noise intensity signals and the working frequency is obtained.

And S1202, determining the working frequency corresponding to the target module as the target working frequency when the noise intensity signal is smaller than the preset threshold value according to the corresponding relation.

After obtaining the correspondence between the noise intensity signal and the operating frequency, it is possible to determine at which operating frequency the noise intensity signal does not affect reception of signals within the operating frequency, based on the correspondence, that is: and when the noise intensity signal is smaller than the preset threshold value, the working frequency corresponding to the target module when the noise intensity signal is smaller than the preset threshold value can be determined as the target working frequency.

In this embodiment, determining the target operating frequency in the above manner is simple and effective, and compared with blind debugging in the prior art, the method in the present disclosure is more efficient.

In this embodiment, optionally, when the noise intensity signal is greater than or equal to the preset threshold, before the adjusting the operating frequency of the target module by the clock frequency adjusting unit corresponding to the target module to obtain the corresponding target operating frequency, the method further includes:

determining that the noise intensity signal is greater than or equal to a preset threshold.

Specifically, the communication device may further include an interference determining unit, and the interference determining unit may determine whether the noise strength signal is greater than or equal to a preset threshold, and start the clock frequency adjusting unit corresponding to the target module when the noise strength signal is greater than or equal to the preset threshold. Correspondingly, if the noise intensity signal is smaller than the preset threshold value, the clock frequency adjusting unit corresponding to the target module does not perform adjusting work.

In this embodiment, by the method, when the clock frequency adjusting unit corresponding to the target module is started can be determined, so that the working frequency of the target module can be adjusted conveniently, and noise is reduced.

In this embodiment, optionally, the determining that the noise intensity signal is greater than or equal to the preset threshold includes:

inputting the noise intensity signal into an amplifier to obtain a corresponding first noise signal;

inputting the first noise signal into a low-pass filter to obtain a corresponding second noise signal;

when the second noise signal is greater than or equal to the preset threshold, determining that the noise intensity signal is greater than or equal to the preset threshold.

Specifically, a noise intensity signal is input into an amplifier, the noise intensity signal can be amplified through the amplifier to obtain a corresponding first noise signal, then the first noise signal is input into a low-pass filter, the low-pass filter can ensure that a low-frequency signal normally passes through the low-pass filter, and a high-frequency signal exceeding a set critical value is blocked and weakened to obtain a corresponding second noise signal; the second noise signal at this time is closer to the actual noise value, which facilitates the subsequent determination of whether the second noise signal is greater than or equal to the preset threshold. When the second noise signal is greater than or equal to the preset threshold, it can be determined that the noise intensity signal is greater than or equal to the preset threshold.

In this embodiment, it is determined that the noise intensity signal is greater than or equal to the preset threshold value in the above manner, interference of other factors can be eliminated, and it is beneficial to subsequently adjust the operating frequency of the target module through the clock frequency adjusting unit corresponding to the target module, so as to obtain the corresponding target operating frequency.

Fig. 3A is a schematic flowchart of another method for reducing noise according to an embodiment of the disclosure. The embodiment is further expanded and optimized on the basis of the above embodiment, wherein one possible implementation manner of S110 is as follows:

s1101, acquiring a noise detection signal of a target module in the communication equipment.

Before reducing noise, firstly, a noise detection signal of a target module in communication equipment needs to be acquired, and specifically, measurement can be performed through corresponding acquisition equipment, so that the noise detection signal is obtained.

S1102, the noise detection signal is mixed with the rf signal output from the oscillator by the mixer.

An oscillator is understood to be an electronic component for generating a repetitive electrical signal (usually a sine wave or a square wave), which is disposed in an rf transceiver chip.

After the noise detection signal of the target module is acquired, the noise detection signal and the radio frequency signal output by the oscillator are mixed by a mixer (i.e., a multiplier), and the noise detection signal and the radio frequency signal output by the oscillator can be combined together.

S1103, the mixed output signal is used as a noise intensity signal.

After the mixing, the signal output after the mixing is used as a noise intensity signal, and the noise intensity signal of the target module in the communication equipment is acquired.

Exemplarily, fig. 3B is a schematic diagram of a connection relationship between a chip and a target module included in a communication device in an embodiment of the present disclosure, and an exemplary connection manner is shown in fig. 3B, as shown in fig. 3B:

it is assumed that the target module is an LCD module and a CAM module, the communication device includes a baseband chip, a radio frequency transceiver chip, an LCD module and a CAM module, and there may be other modules, devices or chips in the communication device, which is not limited in this embodiment.

The LCD module is in communication connection with the baseband chip, and LCD clock and LCD data signal transmission can be carried out between the LCD module and the baseband chip; the LCD module is in communication connection with the radio frequency transceiving chip and transmits an LCD noise detection signal (LCDNoise Detect) to the radio frequency transceiving chip; the CAM module is in communication connection with the baseband chip, and the CAM module and the baseband chip can transmit CAM clock signals and CAM data signals; the CAM module is in communication connection with the radio frequency transceiver chip and transmits a CAM Noise detection signal (CAM Noise Detect) to the radio frequency transceiver chip; the Radio Frequency transceiver chip and the baseband chip are in communication connection, and Radio Frequency (RF) clock signals and RF data signals can be transmitted between the Radio Frequency transceiver chip and the baseband chip.

In this embodiment, optionally, the acquiring a noise detection signal of a target module in the communication device includes:

respectively acquiring data signals and clock signals corresponding to the target module through couplers with a preset number;

and synthesizing all the acquired data signals and clock signals through a power divider to obtain a noise detection signal.

The preset number may be determined according to the number of the data signals and the clock signals corresponding to the target module, or may be determined in other manners, which is not limited in this embodiment. The number of paths of the power divider is the same as the preset number.

Preferably, one path of clock signal corresponds to one coupler, and one path of data signal corresponds to one coupler, so that the source of the noise intensity signal in the target module can be determined according to the opening and closing of the couplers. The number of the paths of the power divider is the same as the preset number, so that errors can be avoided when all collected data signals and clock signals are synthesized through the power divider, and certain paths of signals are prevented from being missed.

In this embodiment, the noise detection signal obtained by the above method is more accurate, and it is convenient to subsequently obtain the noise intensity signal of the target module in the communication device.

For example, fig. 3C is a block diagram of a noise detection signal acquisition device in an embodiment of the disclosure, as shown in fig. 3C:

supposing that n paths of Data signals are respectively Data _1, Data _2 and …, Data _ n and 1 path of Clock signal are Clock, each path of Data signal corresponds to one coupler, the Clock signal corresponds to one coupler, n +1 paths of signals are obtained after passing through the couplers, and the n +1 paths of signals are synthesized through n +1 paths of power dividers to obtain noise detection signals.

For example, fig. 3D is a block diagram of a method for reducing noise of an LCD module according to an embodiment of the present disclosure, as shown in fig. 3D:

assuming that the target module is an LCD module, mixing an LCD noise detection signal output by the LCD module with an RF clock signal output by an oscillator in the RF transceiver chip through a mixer (multiplier) inside the RF transceiver chip to obtain an LCD noise strength signal, where the LCD noise strength signal represents information of interference signal strength. After passing through an amplifier and a low-pass filter, the LCD noise intensity signal is input to an interference judgment unit to judge the size of the LCD noise intensity signal. Under the condition that the LCD noise intensity signal is greater than or equal to a preset threshold (namely, the interference is judged to exist), the purpose of reducing the noise is achieved through the adjustment of the LCD clock frequency adjusting unit.

For example, fig. 3E is a block diagram of a method for reducing noise of a CAM module according to an embodiment of the disclosure, as shown in fig. 3E:

assuming that the target module is a CAM module, the CAM noise detection signal output by the CAM module and the RF clock signal output by the oscillator in the RF transceiver chip are mixed by a mixer (multiplier) inside the RF transceiver chip to obtain a CAM noise strength signal, which represents the information of the interference signal strength. After passing through the amplifier and the low-pass filter, the CAM noise intensity signal is input to an interference judgment unit to judge the magnitude of the CAM noise intensity signal. When the CAM noise intensity signal is greater than or equal to the preset threshold (namely, the interference is judged to exist), the aim of reducing the noise is achieved through the adjustment of the CAM clock frequency adjusting unit.

In this embodiment, compared with the prior art, the method actually tests and judges the size of the noise intensity signal, but the prior art is basically a blind modification, and whether the modification is good cannot be determined in the modification process, and whether the modification is good is known only by performing actual measurement.

In some embodiments, optionally, the method further comprises:

acquiring the closing condition of each coupler in all the couplers;

and determining the source of the noise intensity signal in the target module according to the closed condition.

Wherein, the closed condition comprises two conditions of opening or closing.

Specifically, the plurality of couplers are arranged, and the closing of each coupler can control whether to collect the signal of the corresponding path of the coupler, so that the closing condition of each coupler in all the couplers is obtained, the closing condition of the couplers can be set according to the actual condition, and which path of signal the noise intensity signal in the target module is from can be determined according to different closing conditions.

In the embodiment, the source of the noise intensity signal can be determined, the time cost for radio frequency interference elimination is simplified, workers can conveniently eliminate the interference source in the circuit, and the working efficiency is improved.
