Meanwhile, with the development of terminal intellectualization, more and more peripherals of the terminal are provided, and the peripherals may become interference sources of millimeter waves, for example, many peripherals such as a display screen and a camera can transmit data at a high speed during working, and the high-speed signals can also become interference sources during transmission. The two types of interference sources have the opportunity of falling into a millimeter wave frequency band through higher harmonics and intermodulation generated on a nonlinear device by a transmitting carrier, and become potential interference sources for a millimeter wave receiver. In particular, in the NR CA (Carrier Aggregation) mode, the Sub6G and the CA of millimeter waves, CA between millimeter wave bands, more easily generate an interference source in the millimeter wave band by harmonics and intermodulation.
In the current terminal scheme, the interference sources of millimeter waves are usually processed by means of filtering, grounding shielding or covering with wave-absorbing materials. However, the above measures are often ineffective due to the high frequency, short wavelength and strong directivity of millimeter waves.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.
The embodiment of the invention relates to a millimeter wave anti-interference method, which comprises the steps of adjusting the polarization state of an antenna unit of a terminal according to N groups of preset different polarization parameters in sequence, and acquiring the signal-to-noise ratio corresponding to each group of polarization parameters to obtain N groups of signal-to-noise ratios; and acquiring the maximum signal-to-noise ratio from the N groups of signal-to-noise ratios, and configuring the antenna unit to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio. Because the actual millimeter wave interference received by the terminal is the minimum when the signal-to-noise ratio is the maximum, the antenna unit of the terminal is configured to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio, so that the terminal can adjust the antenna unit of the terminal to the optimal working state according to the millimeter wave interference of the terminal or the surrounding environment, the actual millimeter wave interference received by the terminal is the minimum, the interference of the terminal in using millimeter wave receiving and transmitting signals is reduced, and the millimeter wave interference resistance of the terminal is effectively realized.
It should be noted that the implementation subject of the millimeter wave anti-interference method provided by the embodiment of the present invention is a terminal with variable polarization, and optionally, the terminal is a mobile terminal, such as a mobile phone.
The specific process of the millimeter wave anti-interference method provided by the embodiment of the invention is shown in fig. 1, and comprises the following steps:
s101: the method comprises the steps of adjusting the polarization state of an antenna unit of a terminal according to N preset groups of different polarization parameters in sequence, and obtaining the signal-to-noise ratio corresponding to each group of polarization parameters to obtain N groups of signal-to-noise ratios, wherein N is a positive integer greater than 1, the antenna unit is used for receiving and transmitting signals through millimeter waves, and each group of polarization parameters corresponds to one polarization state of the antenna unit.
The polarization parameters are used for adjusting the polarization states of the antenna units, and each group of polarization parameters corresponds to one polarization state of the antenna unit.
When the antenna unit of the terminal receives and transmits signals by using millimeter waves, a concurrent signal from the terminal or an interference source generated by an external device is a linearly polarized interference source, and the linear polarization direction of the linearly polarized interference source is related to the structure of a radiator with an antenna effect; for interference signals outside the terminal, there is also a certain polarization characteristic, typically linear polarization, and there is also circular polarization, wherein the circular polarization is divided into left-hand circular polarization and right-hand circular polarization. When the linear polarization direction of the interference source signal is consistent (parallel) with that of the terminal antenna unit, the power of the interference source signal entering the receiver through the terminal antenna unit is the strongest, and the millimeter wave interference on the terminal is the largest; when the linear polarization direction of the interference source signal is orthogonal (vertical) to that of the terminal antenna unit, the power of the interference signal entering the receiver through the terminal antenna unit is the weakest, and the millimeter wave interference on the terminal is the smallest; when the linear polarization direction of the interference source and the linear polarization direction of the terminal antenna unit are between parallel and vertical, a certain included angle phi exists between the linear polarization direction of the interference source signal and the linear polarization direction of the terminal antenna unit, the coupling coefficient is | cos Φ |, and the millimeter wave interference on the terminal is between the maximum and the minimum. When the interference source signal is circularly polarized, if the circularly polarized direction of the interference source signal is opposite to the circularly polarized direction of the terminal antenna unit (for example, one is left-handed and the other is right-handed), the coupling coefficient between the interference source signal and the terminal antenna unit is the smallest, the interference signal of the interference source signal entering the receiver through the terminal antenna unit is the weakest, and the millimeter wave interference on the terminal is the smallest; if the circularly polarized direction of the interference source signal is the same as the circularly polarized direction of the terminal antenna unit (for example, both are left-handed), the coupling coefficient is the highest, the interference signal entering the receiver through the terminal antenna unit is the strongest, and the millimeter wave interference on the terminal is the largest.
Optionally, the antenna unit includes a V-polarized antenna element and an H-polarized antenna element, and in a specific example, the configuring, in S101, the antenna unit of the terminal according to N preset groups of different polarization parameters in turn includes: and adjusting the phase and/or amplitude of the V-polarized antenna element sequentially according to the preset N groups of different polarization parameters, and/or adjusting the phase and/or amplitude of the H-polarized antenna element sequentially according to the preset N groups of different polarization parameters so as to adjust the polarization state of the antenna unit.
In particular, reference may be made to fig. 2, which is a diagram illustrating a structure of an antenna unit. In fig. 2, the antenna unit includes two groups of antenna elements, i.e., a V-pole antenna element and an H-pole antenna element, each group of antenna elements is connected to an adjustable phase shifter and an adjustable attenuator, and the combiner is connected to the two groups of adjustable attenuators. The V-polarization antenna oscillator and the H-polarization antenna oscillator respectively represent two groups of orthogonal polarization oscillators in a terminal antenna, are respectively connected into a cascaded adjustable phase shifter and an adjustable attenuator by feeders, and are synthesized by a combiner to form a new polarization signal to be output to a receiver, wherein the adjustable phase shifter generates a phase parameter of the signal, the adjustable attenuator generates an amplitude parameter of the signal, and the phase parameter and the amplitude parameter are jointly called as a polarization parameter of an antenna unit. When the antenna unit is configured according to the preset N groups of different polarization parameters, the phase and/or amplitude of the V-polarization antenna element of the antenna unit is adjusted according to each group of polarization parameters, and/or the phase and/or amplitude of the H-polarization antenna element of the antenna unit is adjusted according to each group of polarization parameters.
It will be appreciated that signals of different polarizations in the plane may be generated by different polarization parameters, and the generation of new polarization signals is illustrated in figure 3, where EVElectric field representing V-polarized signal, EHElectric field representing H-polarized signal, EVAnd EHThe two signals are orthogonal in the XOY plane.
In the X-axis direction of the H vibrator, the electric field vector of the H vibrator is expressed as:
the electric field vector of the V oscillator in the Y-axis direction is expressed as:
the new electric field vector resulting from the two vectors is:
the amplitude is:
the phase is:
when theta isV＝θHOr thetaV＝θHAt +180 deg. the phase of the resultant electric field
Is constant, i.e. the resultant is linear polarization;
when theta isV＝θHAt 90 °, the resultant signal is circularly polarized.
The signal-to-noise ratio SNR is defined as the ratio of the signal level to the noise level:
as can be seen from the above SNR equation, when the useful Signal (Signal) received by the terminal is not changed and the interference Signal (Noise) is reduced, the Signal-to-Noise ratio (SNR) of the received Signal can be improved, thereby improving the Signal quality of the communication link. Since the useful Signal transmitted by the base station is transmitted through a set of orthogonal antennas, the useful Signal (Signal) entering the terminal receiver is not affected by the polarization state of the terminal antenna unit no matter what polarization state the terminal antenna unit is in. The millimeter wave anti-interference method provided by the embodiment of the invention can change the polarization state of the terminal antenna unit by adjusting the phase and amplitude of the V-polarization antenna element and the H-polarization antenna element, so that the polarization correlation between the antenna unit of the terminal and the interference source is minimum, and the Noise (Noise) generated by the interference source can be reduced to the minimum, thereby improving the signal-to-Noise ratio (SNR) of the communication signal. The millimeter wave anti-interference method provided by the embodiment of the invention adjusts the polarization state of the antenna unit of the terminal through the preset N groups of different polarization parameters, can achieve continuous polarization change, synchronously reads the signal-to-noise ratio of the receiver of the terminal in each polarization state, and can select the state with the best signal-to-noise ratio, the polarization of the antenna unit in the state is minimum to the polarization correlation of the interference source, thereby realizing the self-adaptive adjustment of the polarization state of the antenna unit of the terminal, ensuring that the polarization correlation between the antenna unit of the terminal and the polarization state of the interference source is minimum as much as possible, and achieving the purpose of anti-interference.
It can be understood that, when the number N of sets of preset polarization parameters is larger, it is easier to minimize the millimeter wave interference received by the terminal, but at the same time, the time for determining the maximum signal-to-noise ratio is increased.
In a specific example, the signal-to-noise ratio corresponding to each set of polarization parameters is obtained in S101, specifically, after the antenna unit is configured with a set of polarization parameters, a signal received by a receiver of the terminal is detected to obtain the signal-to-noise ratio corresponding to the current polarization parameter, where the receiver is connected to the antenna unit.
That is, the snr corresponding to each set of polarization parameters is obtained by detecting the snr of the receiver. The receiver of the terminal is configured to receive a signal that reaches the terminal, and the signal received by the receiver includes a signal that is received and transmitted by the antenna unit and also includes a signal of an interference source, so that the signal-to-noise ratio corresponding to each group of polarization parameters can be effectively obtained by detecting the signal-to-noise ratio of the receiver.
S102: and acquiring the maximum signal-to-noise ratio from the N groups of signal-to-noise ratios.
Optionally, when the terminal adjusts the polarization state of the antenna unit of the terminal according to each group of polarization parameters, the signal-to-noise ratio corresponding to each group of polarization parameters may be recorded, and after the polarization parameters of all groups are scanned, the largest signal-to-noise ratio is screened out from the recorded signal-to-noise ratios.
S103: and configuring the antenna unit to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio.
When the polarization parameters corresponding to the maximum signal-to-noise ratio are a group, directly configuring the antenna unit according to the group of polarization parameters; when the polarization parameters corresponding to the maximum signal-to-noise ratio are two or more groups, a group of polarization parameters can be selected randomly or according to the using sequence of the polarization parameters to configure the antenna unit to work.
In a specific example, the millimeter wave interference rejection method provided in the embodiment of the present invention may further include: and circularly executing S101-S103 according to the preset work period.
The preset duty cycle may be set according to actual needs, for example, 1 second, 10 seconds, and the like, and is not limited herein. Since the shorter the preset working period is set, the more easily the terminal makes an optimal adjustment according to the received millimeter wave interference, but the more easily the resource occupation of the terminal is increased, the preset can be performed in combination with the bearable degree of the millimeter wave interference and the resource occupation in the preset working period. It should be understood that the time from adjusting the polarization state of the antenna unit according to the preset N sets of different polarization parameters to obtaining N sets of snr is relatively short, and can be used as a process of debugging and scanning, and the time of the process occupies a smaller proportion of the preset working period; after the maximum signal-to-noise ratio is determined and the antenna unit is configured to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio, the antenna unit works according to the polarization parameter in the rest time of the preset working period.
Specifically, when a preset working period starts, the polarization state of the terminal is sequentially adjusted according to N preset groups of different polarization parameters, the signal-to-noise ratio corresponding to each group of polarization parameters is obtained, N groups of signal-to-noise ratios are obtained, the maximum signal-to-noise ratio is obtained from the N groups of signal-to-noise ratios, the antenna unit is configured according to the polarization parameter corresponding to the maximum signal-to-noise ratio to work until the current preset working period is finished, then the next preset working period is started, and the steps are repeated in a circulating manner.
It can be understood that, because the surrounding environment of the terminal may change, for example, when the location of the terminal changes, or when the peripheral of the terminal changes from non-operating to operating, the surrounding environment of the terminal may change at any time, so that the maximum signal-to-noise ratio is determined according to the preset operating cycle, the terminal may be more easily adjusted in time according to the actual millimeter wave interference condition, and a condition with better millimeter wave interference resistance is maintained.
Please refer to fig. 4, which is a flowchart illustrating a millimeter wave anti-interference method according to an embodiment of the present invention. The specific process can include:
1. the terminal establishes millimeter wave signaling connection; 2. the terminal establishes a timer according to a preset working period t; 3. the terminal sequentially transmits N groups of preset different polarization parameters to an antenna unit of the terminal, and after each group of polarization parameters is transmitted, the terminal synchronously acquires the signal-to-noise ratio corresponding to the current group of polarization parameters, so that the scanning of the signal-to-noise ratios corresponding to all the groups of polarization parameters is completed; 4. the terminal screens out polarization parameters corresponding to the maximum signal-to-noise ratio from the scanning result, and configures the polarization parameters into an antenna unit of the terminal to be used as the polarization working state of the residual time of the current preset working period t; 5. and when the current preset working period is finished, restarting the timer to carry out the next preset working period. The above processes are circularly performed in the whole millimeter wave signaling connection working state.
In the prior art, the interference sources of millimeter waves are processed by adopting modes such as filtering, grounding shielding or covering wave-absorbing materials, so that the effect is very little, the structure of the terminal is more complex, and the layout of the structure is limited. For example, when the filtering method is used for processing, the filtering module is added, so that the structural complexity of the terminal is increased, the hardware cost is increased, and the problem of insertion loss is also caused. The millimeter wave anti-interference method provided by the embodiment of the invention does not change the structure of the terminal, so that the complexity of the structure of the terminal is not increased, and the problems of hardware cost increase or insertion loss and the like are not caused.
According to the millimeter wave anti-interference method provided by the embodiment of the invention, the polarization state of an antenna unit of a terminal is adjusted according to N groups of preset polarization parameters, and the signal-to-noise ratio corresponding to each group of polarization parameters is obtained to obtain N groups of signal-to-noise ratios; and acquiring the maximum signal-to-noise ratio from the N groups of signal-to-noise ratios, and configuring the antenna unit to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio. Because the actual millimeter wave interference on the terminal is the minimum at the maximum signal-to-noise ratio, the antenna unit of the terminal is configured to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio, so that the actual millimeter wave interference on the terminal can be the minimum, the interference on the terminal when the millimeter wave receiving and transmitting signals are used is reduced, and the millimeter wave interference resistance of the terminal is effectively realized; meanwhile, the structure of the terminal does not need to be changed, so that the complexity of the structure of the terminal cannot be increased, and the problems of hardware cost increase or insertion loss and the like of the terminal cannot be caused.
A second embodiment of the present invention relates to a millimeter wave interference rejection method, and is substantially the same as the first embodiment, and mainly differs therefrom in that: after configuring the antenna unit to operate according to the polarization parameter corresponding to the maximum snr, the method further includes: and detecting the receiver according to a preset time interval, and if the difference between the detected signal-to-noise ratio and the maximum signal-to-noise ratio is greater than a preset threshold value, returning to the step of executing the step of adjusting the polarization state of the antenna unit of the terminal according to N groups of preset different polarization parameters.
The specific flow of the millimeter wave anti-interference method provided by the embodiment of the invention is shown in fig. 5, and specifically comprises the following steps:
s201: the method comprises the steps of adjusting the polarization state of an antenna unit of a terminal according to N preset groups of different polarization parameters in sequence, and obtaining the signal-to-noise ratio corresponding to each group of polarization parameters to obtain N groups of signal-to-noise ratios, wherein N is a positive integer greater than 1, the antenna unit is used for receiving and transmitting signals through millimeter waves, and each group of polarization parameters corresponds to one polarization state of the antenna unit.
S202: and acquiring the maximum signal-to-noise ratio from the N groups of signal-to-noise ratios.
S203: and configuring the antenna unit to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio.
S204: and detecting the receiver according to a preset time interval.
S205: and judging whether the difference between the detected signal-to-noise ratio and the maximum signal-to-noise ratio is greater than a preset threshold, if so, returning to execute S201, and otherwise, returning to execute S204.
S201 to S203 are the same as S101 to S103 in the first embodiment, and reference may be specifically made to the related description in the first embodiment, and details are not repeated here to avoid repetition.
For S204-S205, the details are as follows:
similar to the preset working period, when the preset time interval is set to be shorter, the terminal is easier to adjust timely according to the actual millimeter wave interference condition, but the occupation of the resource of the terminal is also increased, so that the preset time interval can be set in combination with the bearable degree of millimeter wave interference and the occupation condition of the resource of the terminal. The preset threshold is also similar, and as the smaller the preset threshold is set, the easier the terminal is to change in time according to the actual change situation of the received millimeter wave interference, but the more frequently the terminal adjusts the antenna unit according to the preset N groups of different polarization parameters, the more the occupation of the resources of the terminal is increased, so the preset threshold can also be set in combination with the anti-interference precision of the millimeter wave and the occupation situation of the resources of the terminal, and no specific limitation is made here.
Specifically, after configuring an antenna unit to work according to a polarization parameter corresponding to a maximum signal-to-noise ratio, a terminal detects a receiver according to a preset time interval to detect a working state of the antenna according to the polarization parameter corresponding to the maximum signal-to-noise ratio; if the detected signal-to-noise ratio is different from the maximum signal-to-noise ratio by more than a preset threshold value, returning to execute S201, readjusting the polarization state of the antenna unit of the terminal according to N preset groups of different polarization parameters, and reacquiring the signal-to-noise ratio corresponding to each group of polarization parameters (namely, reacquiring the scanning of the polarization parameters), and reacquiring N groups of signal-to-noise ratios; then, the maximum signal-to-noise ratio is obtained again from the N groups of signal-to-noise ratios obtained again, and the antenna unit is configured to work according to the polarization parameters corresponding to the maximum signal-to-noise ratio determined again; if the difference between the detected signal-to-noise ratio and the maximum signal-to-noise ratio is smaller than or equal to the preset threshold, the process returns to step S204, and at this time, the antenna unit maintains the previous polarization parameters unchanged, and the polarization state of the antenna unit does not need to be adjusted again according to the N groups of different polarization parameters.
The millimeter wave anti-interference method provided by the embodiment of the invention detects a receiver of a terminal according to a preset time interval after configuring an antenna unit to work according to the polarization parameter corresponding to the maximum signal-to-noise ratio, returns to the previous step to re-determine the maximum signal-to-noise ratio if the difference between the detected signal-to-noise ratio and the previous maximum signal-to-noise ratio is greater than a preset threshold value, configures the antenna unit to work according to the polarization parameter corresponding to the re-determined maximum signal-to-noise ratio, and otherwise continues to detect the receiver of the terminal according to the preset time interval. On one hand, when the difference between the detected signal-to-noise ratio and the previous maximum signal-to-noise ratio is larger than a preset threshold value, the maximum signal-to-noise ratio is determined again, the antenna unit is configured to work according to the determined maximum signal-to-noise ratio, and when the millimeter wave interference received at a certain moment is greatly changed, the terminal can make adaptive adjustment in time according to the actual millimeter wave interference condition, so that the millimeter wave interference received by the terminal is reduced; on the other hand, because the antenna unit is reconfigured again according to the preset N groups of different polarization parameters corresponding to the signal-to-noise ratio when the detected signal-to-noise ratio and the previous signal-to-noise ratio are greater than the preset threshold, and the working state of the antenna unit can be maintained when the detected signal-to-noise ratio and the previous signal-to-noise ratio are less than or equal to the preset threshold, the terminal does not need to adjust the antenna unit according to the preset N groups of different polarization parameters frequently, the working process of the antenna unit is simplified, and the occupation of terminal resources is reduced.
In addition, those skilled in the art can understand that the steps of the above methods are divided for clarity, and the implementation can be combined into one step or split into some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, and the method is within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
