Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The control method, the control device, the WIFI radio frequency circuit and the electronic device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart of a control method provided in an embodiment of the present application, where the control method in the embodiment is applied to a WIFI radio frequency circuit, and as shown in fig. 1, the method includes:
The system may also be referred to as a modulation mode, and the WIFI radio frequency circuit has a plurality of different systems, and the different systems may include: at least one of Modulation schemes such as Quadrature Amplitude Modulation (QAM) and Phase-Shift Keying (PSK).
Optionally, before determining the target standard, the method further includes:
under a first standard, setting the working voltage of the power amplifier as a first voltage;
determining a first compression point according to the first voltage;
determining a first power from the first compression point;
and establishing a preset corresponding relation among the first voltage, the first compression point and the first power.
In this way, the preset corresponding relationship between the first system and the first voltage, the first compression point and the first power can be determined through the embodiment, and in the subsequent use process, the first voltage, the first compression point and the first power corresponding to the first system can be directly determined according to the preset corresponding relationship only by determining the type of the first system of the WIFI radio frequency circuit, so that the working performance of the WIFI radio frequency circuit is enhanced.
Of course, as an alternative embodiment, the above embodiment may also be understood as the following process:
traversing the working voltage corresponding to the target system to obtain a target voltage;
traversing the compression point corresponding to the target voltage to obtain a target compression point;
traversing the power corresponding to the target compression point to obtain target power;
and establishing a preset corresponding relation among the target system, the target voltage, the target compression point and the target power.
In this way, due to the fact that the preset corresponding relation among the target system, the target voltage, the target compression point and the target power is established, after the target system is determined, the corresponding target working information can be determined quickly and accurately, and the processing speed is improved.
The flowchart for establishing the preset corresponding relationship among the target system, the target voltage, the target compression point and the target power may specifically refer to fig. 2.
The system in the embodiment of the present application may also be referred to as modulation, and the power may include at least one of input power and output power.
The value of the target system is not limited herein, and the target system may select each system in turn, traverse the corresponding relationship between each system and each operating voltage, each compression point and each power, and store the corresponding relationship.
For example: optionally, after the establishing of the preset correspondence between the first voltage, the first compression point, and the first power, the method further includes:
and storing the preset corresponding relation to a server or a memory.
The WIFI radio frequency circuit and the memory can be parts in the electronic equipment, and the WIFI radio frequency circuit can be electrically connected with the memory.
Therefore, the preset corresponding relation is stored in the server or the memory, so that the backup of the preset corresponding relation can be realized, and the subsequent acquisition of the preset corresponding relation is more convenient.
Optionally, before the setting the operating voltage of the power amplifier to the first voltage in the first system, the method further includes:
and switching the radio frequency channel of the WIFI radio frequency circuit to a target radio frequency channel, wherein the target radio frequency channel is a radio frequency channel with optimal performance in the radio frequency channel of the WIFI radio frequency circuit.
The radio frequency path with the best performance may refer to a radio frequency path with the best transmission performance, and the transmission performance may include at least one of the fastest transmission speed and the shortest transmission time.
In the embodiment of the application, the radio frequency channel of the WIFI radio frequency circuit is switched to the target radio frequency channel, so that the emission performance of the WIFI radio frequency circuit can be further enhanced.
And 102, determining target working information corresponding to the power amplifier according to the target system, wherein different systems correspond to different target working information, and the target working information comprises working voltage, compression point and power which correspond to one another.
When the WIFI radio frequency circuit works, a target system needs to be determined. The information such as the rate and the power corresponding to different systems is different, for example: referring to table 1, in a High-efficiency wireless standard (HEW), a rate corresponding to a QAM may be MCS11, and a power corresponding to MCS11 may be 13; the rate corresponding to PSK may be MCS0, and the power corresponding to MCS0 may be 20, which is only exemplary and not limited herein.
TABLE 1
In addition, referring to fig. 3, the correspondence between the standard (which may also be referred to as modulation) and the coding rate and relative constellation error. The modulation may be referred to as modulation, the code rate may be referred to as coding rate, and the relative constellation error may be referred to as relative constellation error. Note that the unit of the relative constellation error may be db.
The high-efficiency wireless standard may also be referred to as wifi6 or IEEE 802.11 ax.
Among them, the compression point can be referred to the following expression: a power amplifier may be included in the WIFI radio frequency circuit, and the compression point of the WIFI radio frequency circuit may refer to the compression point of the power amplifier,
in addition, the modes, the working voltages, the compression points and the powers of the WIFI radio frequency circuit can be in one-to-one correspondence, so that the working voltage, the compression points and the power corresponding to a certain mode are different from those corresponding to other modes, the working voltages, the compression points and the powers of the WIFI radio frequency circuit can be determined under each mode, and the intelligent degree of the WIFI radio frequency circuit is enhanced.
It should be noted that, the correspondence between each system and the corresponding working voltage, compression point, and power may be preset, and when the WIFI radio frequency circuit is in the working state of the working voltage, compression point, and power included in the target working information corresponding to each system, the radio frequency performance of the WIFI radio frequency circuit is better.
As an optional implementation manner, in a case that the target system is a first system, a working voltage corresponding to the first system is less than or equal to a rated voltage, a compression point corresponding to the first system is greater than a rated compression point, and a power corresponding to the first system is greater than a rated power;
or, in a case that the target system is a second system, a working voltage corresponding to the second system is greater than a rated voltage, a compression point corresponding to the second system is less than or equal to a rated compression point, and a power corresponding to the second system is less than or equal to a rated power.
Therefore, different target working information can be selected according to different target systems where the WIFI radio frequency circuit is located, the working flexibility and the intelligent degree of the WIFI radio frequency circuit are enhanced, and meanwhile the transmitting performance of the WIFI radio frequency circuit can be further enhanced.
The first format may be referred to as a medium-low order format, and the second format may be referred to as a high order format.
It should be noted that, when the WIFI radio frequency circuit is in a working state of a medium-low order system, the linearity requirement of the WIFI radio frequency circuit on the power amplifier is low, and most working states of the WIFI radio frequency circuit are of the medium-low order system, therefore, when the target system is of the medium-low order system, a working voltage included in target working information corresponding to the target system may be low (i.e., lower than a rated voltage), a compression point may be high (higher than a rated compression point), and power may meet the requirement (i.e., higher than a rated power), specifically, see fig. 4, and when the target system is of the medium-low order system, a corresponding parameter of an object shown by a point a in fig. 4 may be selected. Therefore, the power consumption of the WIFI radio frequency circuit can be reduced.
When the target system is a high-order system, the WIFI radio frequency circuit has a high requirement on the linearity of the power amplifier, and at this time, the transmission performance of the WIFI radio frequency circuit is preferentially considered, so that the target working information corresponding to the target system includes a low compression point (lower than a rated compression point), a high working voltage (higher than a rated voltage), and a high power (which may be higher than the target power but less than or equal to the rated power). For example: corresponding parameters of the object shown by point B in fig. 4 may be selected, which may improve the transmission performance of the WIFI radio frequency circuit.
In addition, E in fig. 4 represents the input and output power curves of the power amplifier in the WIFI radio frequency circuit at a certain operating voltage, D represents the operating efficiency curve of the power amplifier, and the abscissa in fig. 4 represents the input power and the ordinate represents the output power. C represents the maximum decrease amplitude of power added efficiency (large drop in PAE), and point a in fig. 4 represents the peak occurrence position of PAE.
As can be seen from fig. 4, the working efficiency of the power amplifier generally reaches the highest in the saturation region, that is, the working efficiency at the compression point of the power amplifier is greatly improved, so that, under a specific voltage, the point corresponding to the input power and the output power that satisfy the requirement of a certain compression point is unique, and when the output power of the power amplifier is smaller than the output power of the compression point, the working efficiency of the power amplifier is low.
As an optional implementation manner, the WIFI radio frequency circuit can be powered by a battery, that is, the battery can be electrically connected with the WIFI radio frequency circuit, so that the rated voltage of the WIFI radio frequency circuit can refer to the rated voltage of the battery, the working voltage of the WIFI radio frequency circuit is increased to be higher than the rated voltage of the battery, and the safety performance of the WIFI radio frequency circuit can be ensured on the premise of improving the emission performance of the WIFI radio frequency circuit. Certainly, the difference between the rated voltage of the WIFI radio frequency circuit and the rated voltage of the battery should be within the preset threshold, so that the safety of battery power supply can be ensured.
In an embodiment of the present application, a power amplifier control method includes: determining a target system; and determining target working information corresponding to the power amplifier according to the target system, wherein different systems correspond to different target working information, and the target working information comprises working voltage, compression point and power which are in one-to-one correspondence. Therefore, each system has corresponding working voltage, compression point and power, and when the WIFI radio frequency circuit is in a working state corresponding to the working voltage, the working efficiency is high, so that the working performance of the WIFI radio frequency circuit is improved.
In addition, in the embodiment of the application, the requirements on linearity are different due to different systems, so that the working voltage of the power amplifier can be adjusted according to the systems, the working efficiency of the power amplifier is improved, and the power consumption is reduced. When the WIFI radio frequency circuit is in a high-order system, the working voltage of the power amplifier is higher than the voltage of a battery, so that the performance of the radio frequency circuit can be improved; in addition, envelope tracking is not needed, and the voltage and the input power of the power amplifier can be adjusted according to the system.
