[0025] To facilitate the explanation, some nouns or terms related to the embodiments of the present disclosure will be explained below.

[0026] TCON is an abbreviation for a timing controller.

[0027] As described in the background information, the prior art has a technical problem in the actual system application of electronic equipment in which EMI from the operation and communication of chips other than the conventional wireless communication chip affects the normal wireless communication function. To solve the above problem, a typical embodiment of this disclosure provides a method and apparatus for adjusting harmonic parameters, a processor, and an electronic device.

[0028] The embodiments of this disclosure provide a method for adjusting harmonic parameters.

[0029] Figure 1 is a flowchart of a method for adjusting harmonic parameters according to an embodiment of the present disclosure. As shown in Figure 1, the method includes the following steps S101 to S103.

[0030] In step S101, the target signal is determined, which is the communication signal that the device's processor is currently interacting with other devices.

[0031] In step S102, multiple harmonics corresponding to multiple chips are determined, and it is determined whether or not a target harmonic exists among the multiple harmonics. The target harmonic is a harmonic that interferes with the target signal, and the multiple chips are mounted in the device.

[0032] In step S103, if a target harmonic exists, the harmonic parameters of the target harmonic are adjusted to the target harmonic parameters.

[0033] Taking a laptop as an example, it needs to support various frequency bands such as Wi-Fi, LTE 4G, 5G, and Bluetooth, and switch between these various frequency bands. The wireless communication antenna of a laptop is located behind the display screen, and as such, it is susceptible to EMI caused by TCON, which can affect normal operation.

[0034] Accordingly, the present disclosure provides a method for adjusting the above-mentioned harmonic parameters, which involves determining the wireless communication currently being used by the device, determining harmonics transmitted from other chips in the device, determining harmonics that interfere with the communication signal currently being used by the device, and reducing or eliminating interference of the interfering harmonics to the target signal by adjusting the parameters of the interfering harmonics.

[0035] In a preferred embodiment, the step of determining a plurality of harmonics corresponding to a plurality of chips and determining whether or not a target harmonic is present among the plurality of harmonics includes the steps of determining a plurality of harmonic frequency bands corresponding to the plurality of harmonics, calculating a plurality of frequency band differences between the plurality of harmonic frequency bands and a target frequency band, and determining a plurality of absolute values ​​of frequency band differences corresponding to the plurality of frequency band differences, wherein the target frequency band is the communication frequency band corresponding to the target signal, one frequency band difference corresponds to one absolute value of frequency band difference, and the absolute value of frequency band difference is the absolute value of frequency band difference, and determining whether or not a target harmonic is present among the plurality of harmonics based on the plurality of absolute values ​​of frequency band differences.

[0036] In a preferred embodiment, the step of determining whether a target harmonic exists among a plurality of harmonics based on a plurality of absolute frequency band differences includes the step of determining whether a target absolute frequency band difference exists among a plurality of absolute frequency band differences, wherein the target absolute frequency band difference is an absolute frequency band difference within a predetermined frequency band range, and if a target absolute frequency band difference exists, the step of determining that the harmonic corresponding to the target absolute frequency band difference is the target harmonic.

[0037] As described above, the target frequency band corresponding to the target signal is determined, the absolute value of the frequency band difference between the frequency band corresponding to the harmonics generated from each other chip and the target frequency band is calculated, and based on the absolute value of the frequency band difference, it is determined which harmonics interfere with the target signal.

[0038] In addition to the method for determining the interfering harmonics that interfere with the target signal using the method described above, the method further includes determining which harmonics interfere with the target signal based on the operating clock of the target signal and the clocks corresponding to the harmonics, and the specific steps include the following steps 201 to 203, as shown in Figure 2.

[0039] In step S201, the target operating clock of the processor is determined. In step S202, multiple harmonic clocks corresponding to multiple harmonics are determined, one harmonic corresponds to one harmonic clock, and the harmonic clock is the clock of the corresponding harmonic. In step S203, it is determined whether the target harmonic is present in the multiple harmonics based on the target operating clock and the multiple harmonic clocks.

[0040] More specifically, the system determines whether any of the multiple harmonic clocks affect the target operating clock, and if one or more of the multiple harmonic clocks affect the target operating clock, the harmonic corresponding to that harmonic clock is determined as the target harmonic.

[0041] In the method relating to this disclosure, after determining a target signal, the method further includes the step of broadcasting the target signal to timing controllers corresponding to multiple chips and devices. By broadcasting the information, the other chips and timing controllers receive the communication signals used by the devices, transmitted from the CPU.

[0042] In a preferred embodiment, if there is a target harmonic, the step of adjusting the harmonic parameters of the target harmonic to the target harmonic parameters includes the step of adjusting the clock of the target chip to a target clock, wherein the target harmonic does not affect the communication signal, and the target chip is a chip that transmits the target harmonic; or the step of adjusting the spred spectrum of the target harmonic to a target spred spectrum, wherein the target spred spectrum distributes the energy corresponding to the target harmonic within a predetermined range; or the step of adjusting the clock of the target chip to a target clock and adjusting the spred spectrum of the target harmonic to a target spred spectrum.

[0043] As described above, in the method of this disclosure, by adjusting the operating clock of the target harmonic, a large difference is created between the operating clock of the harmonic and the operating clock of the target signal. In this way, interference of the target harmonic with the communication signal can be reduced. At the same time, the spread spectrum of the target harmonic can be adjusted, and by spreading the spread spectrum, the energy of the target harmonic can be dispersed within a single range, thereby reducing interference of the target harmonic with the target signal.

[0044] The method for adjusting harmonic parameters described herein solves EMI problems, and at the same time, the method has the advantages of being low-cost, highly flexible, and highly scalable. Furthermore, it can provide a unified solution based on an algorithm and is easily applicable to various items.
