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.

In order to more fully understand the technical solutions provided by the embodiments of the present application, the following contents are introduced:

at present, with the continuous update of Wi-Fi technology, the performance of Wi-Fi is mainly limited by hardware schemes and the evolution speed of Wi-Fi protocols. Generally, improving Wi-Fi performance on software algorithms is less costly and easier to implement than improving on hardware solutions. The signal quality of the TX signal is improved through an LO leakage compensation algorithm, an IQ compensation algorithm, a DPD algorithm and the like in Wi-Fi calibration, and lower OFDM peak-to-average ratio, lower EVM and lower phase fluctuation are obtained.

Generally, the Wi-Fi parameters are obtained by averaging a plurality of mainboard parameters through some calibration algorithms to obtain board parameters, the board parameters are written into the mobile terminal equipment, and then the mobile terminal under the same scheme uses the set of parameters and combines with a Wi-Fi internal self-calibration algorithm to realize the control of Wi-Fi emission signals.

Wi-Fi emission signal control:

self-calibration flow: the Wi-Fi module transmits the gains of each level of PA and BB (Base Band, reference bandwidth) according to the set expected power through an internal coupling path, and deduces the size and calibration of a transmitted signal through the coupled parameters; the built-in parameter table is a table for storing the gains of all levels of the PA and the corresponding BB output power calibrated by a few single boards, the actual PA gain state and the BB baseband using the power table are different, and the actual output power of the antenna port cannot reach the target power. The difference exists between different mobile phones, and the difference of the front ends can cause the performance difference to be larger under the same parameters.

As shown in fig. 2, the power of a single device is calibrated to obtain a power table of the single device, which is usually made as N (generally <20 devices), then the gain (gain) states of the PAs and the gain states of the BB in the N power tables are unified to obtain a golden board parameter of the power, and then the golden board parameter of the power is integrated into software, and all devices call the golden board parameter of the power to obtain the target power.

FIG. 4 is a schematic flow chart diagram of a Wi-Fi signal transmission power calibration method according to an embodiment of the application; referring to fig. 4, on the basis of the foregoing Wi-Fi signal transmission power calibration system in various embodiments, an embodiment of the present application further provides a Wi-Fi signal transmission power calibration method, which may include:

step 410, determining the actual signal transmitting power of Wi-Fi under the condition that the movable end of the first switch S1 is electrically connected with the first passage P1 and the movable end of the second switch S2 is electrically connected with the first passage P1;

and step 420, calibrating the Wi-Fi signal transmission power according to the set signal transmission power and the actual signal transmission power of the Wi-Fi.

The execution subject of the Wi-Fi signal transmission power calibration method in the embodiment of the application can be an electronic device, a component in the electronic device, an integrated circuit, or a chip. The electronic device may be a mobile electronic device or a non-mobile electronic device. By way of example, the mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile electronic device may be a server, a Network Attached Storage (NAS), a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiments of the present application are not particularly limited.

The following describes the technical solution of the present application in detail by taking an example in which a mobile phone executes the Wi-Fi signal transmission power calibration method provided in the embodiments of the present application.

Under the condition that the movable end of the first switch S1 is electrically connected with the first path P1 and the movable end of the second switch S2 is electrically connected with the first path P1, the mobile phone can obtain the actual signal transmission power of Wi-Fi at least in one of the following modes:

mode A: determining the actual signal transmission power according to the second signal transmission power detected by the second power detection module 222;

it can be understood that, after the Wi-Fi of the mobile phone outputs the set signal transmission power S through the DA, the set signal transmission power S is transmitted through the antenna AN after passing through the back-end module 1, the first switch S1, the first path P1, the power coupler 210, and the third path P3. Correspondingly, the second power detection module 222 may detect the transmission power of the antenna, and at this time, the second signal transmission power detected by the second power detection module 222 may be used as the actual signal transmission power S of the Wi-Fi.

As shown in fig. 3, a third power detection module 223 may be additionally disposed in the Wi-Fi signal transmission power calibration system, or an existing Wi-Fi power detection module may be used to detect the set signal transmission power s.

The third power detection module 223 may be electrically connected to the DA of Wi-Fi through a fifth path P5. When the Wi-Fi outputs the set signal transmission power s through the DA, the transmission power s may be coupled back to the third power detection module 223 through the fifth path P5, so that the third power detection module 223 may detect the set signal transmission power s.

Mode B: the actual signal transmission power is determined according to the first signal transmission power detected by the first power detection module 221 and the corresponding relationship between the first detection value of the first power detection module 221 and the second detection value of the second power detection module 222.

The correspondence relationship may be obtained as follows:

under the condition that the moving end of the second switch S2 is electrically connected to the reference module 2, acquiring a first reference power a detected by the first power detection module 221 and a second reference power B detected by the corresponding second power detection module 222;

and determining the corresponding relation according to the first reference power A and the second reference power B.

When the moving terminal of the second switch S2 is electrically connected to the reference module 2, the reference module 2 may emit power, and the power may be caused to reach the first power detection module 221 (first reference power a) and reach the second power detection module 222 (second reference power B) by the coupling of the power coupler 210.

By repeating the above steps, a plurality of first reference powers a and a plurality of corresponding second reference powers B can be obtained. Then, the correspondence relationship between a and B can be obtained from the plurality of first reference powers a and the corresponding plurality of second reference powers B. For example, the correspondence between a and B can be obtained by means of linear fitting.

Note that, in the case where the execution subject is a communication device such as a mobile phone or a Pad, the reference module 2 may be a 4G or 5G module.

Because the calibration precision of the 4G or 5G module is higher and the devices in the module are more stable, when the reference module 2 is the 4G or 5G module, on one hand, the existing structure of the execution main body can be utilized, so that the structure of the Wi-Fi signal transmission power calibration system is simplified, and the cost is saved; on the other hand, the accuracy of the corresponding relation between the first reference power A and the second reference power B can be ensured, and the accuracy of Wi-Fi signal transmission power calibration is further improved.

Further, as shown in fig. 3, the first power detection module 221 may also be an existing power detection module inside a 4G or 5G module, so as to further simplify the structure of the Wi-Fi signal transmission power calibration system and save cost.

After determining the corresponding relationship between the first reference power a and the second reference power B, the mobile phone may determine the actual signal transmission power S of the Wi-Fi based on the corresponding relationship between the first reference power a and the second reference power B according to the first signal transmission power a detected by the first power detection module 221.

In one embodiment, step 420 may include:

determining a target corresponding relation between the set signal transmitting power S and the actual signal transmitting power S according to the set signal transmitting power S and the corresponding actual signal transmitting power S;

and calibrating the signal transmitting power of the Wi-Fi according to the target signal transmitting power T of the Wi-Fi and the target corresponding relation.

Wherein, the target signal transmitting power T refers to the signal transmitting power which needs to be actually achieved by the Wi-Fi.

The target corresponding relation between S and S can be obtained by a plurality of set signal transmitting powers S and a plurality of corresponding actual signal transmitting powers S. For example, the target correspondence of S and S can be obtained by means of linear fitting.

After the target corresponding relation between S and S is determined, the mobile phone can adjust the transmitting power of Wi-Fi according to the set signal transmitting power S corresponding to the target signal transmitting power T (S ═ T), so that the transmitting power error of Wi-Fi caused by the difference of the back-end module 1 is accurately controlled.

The Wi-Fi signal transmitting power calibration system and method provided by the embodiment of the application can accurately calibrate the error of the Wi-Fi signal transmitting power caused by the difference of the rear-end module 1 through simple external circuit design and algorithm, and have the technical effects of simplicity in implementation and high calibration precision.

To further facilitate understanding of the technical solutions provided in the embodiments of the present application, the following describes a Wi-Fi signal transmission power calibration system and method provided in the embodiments of the present application with specific examples:

example one:

step 1), using default parameters, starting up to carry out default flow calibration, and correcting a path before DA;

step 2), the second switch S2 is switched to the second path P2, the reference module 2 transmits a signal, and the signal is coupled to the first power detection module 221 through the power coupler 210 via the fourth path P4 to obtain power a, and at the same time, the transmitted power is transmitted from the antenna AN via the third path P3, and at this time, the second power detection module 222 detects power B; establishing a linear relation table of A and B, and storing;

step 3), the first switch S1 is switched to the antenna AN, the Wi-Fi sends out power S, the power S ' is coupled to the third power detection module through the fifth path P5 to obtain power S ', a linear relation table of the power S and the power S ' is established and stored;

step 4), the first switch S1 is switched to the first path P1 and the second switch S2 is switched to the first path P1, Wi-Fi emits power S, which is coupled to the first detection module 221 via the path 4 to obtain power a; the actual Wi-Fi signal transmitting power S can be calculated based on the power a and the linear relation between A and B;

step 5), obtaining the signal transmitting power deviation caused by the rear-end module 2 through the difference fitting of S and S', and calibrating the Wi-Fi signal transmitting power based on the deviation;

and 6) repeating the steps 2) to 5) to dynamically calibrate the signal transmission power of the Wi-Fi.

Example two:

step 5), establishing a corresponding relation table of S and S and storing;

and 6) when the Wi-Fi works, updating the corresponding relation table of S and S at regular time through timing or triggering conditions, so as to dynamically calibrate the signal transmitting power of the Wi-Fi.
