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

[0026] TCON is an abbreviation for timing controller.

[0027] As described in the background art, the prior art has a technical problem that in actual system applications of electronic devices, EMI caused by the operation and communication of chips other than conventional wireless communication chips affects normal wireless communication functions. In order to solve the above problem, in an exemplary embodiment of the present disclosure, a method and apparatus for adjusting harmonic parameters, a processor, and an electronic device are provided.

[0028] According to an embodiment of the present disclosure, a method for adjusting a harmonic parameter is provided.

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

[0030] In step S101, a target signal is determined, the target signal being a communication signal with which the processor of the device is currently interacting with another device.

[0031] In step S102, a plurality of harmonics corresponding to a plurality of chips are determined, and it is determined whether there is a target harmonic among the plurality of harmonics, the target harmonic being a harmonic that causes interference to a target signal, and the plurality of chips are implemented in the equipment.

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

[0033] Take a laptop as an example, it needs to support various frequency bands such as WIFI, LTE 4G, 5G, Bluetooth, etc., and can switch between various frequency bands. The wireless communication antenna of the laptop is located behind the display screen, so the EMI caused by the TCON is likely to affect normal use.

[0034] Therefore, the present disclosure provides a method for adjusting the above-mentioned harmonic parameters, which determines the wireless communication currently used by the device, determines the harmonics transmitted from other chips in the device, and determines the harmonics that interfere with the communication signal currently used by the device, and adjusts the parameters of the interfering harmonics to reduce or eliminate the interference of the interfering harmonics with the target signal.

[0035] In a preferred embodiment, the step of determining a plurality of harmonics corresponding to a plurality of chips and determining whether the plurality of harmonics has a target harmonic 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, respectively, and determining a plurality of frequency band difference absolute values ​​corresponding to the plurality of frequency band differences, where the target frequency band is a communication frequency band corresponding to a target signal, one frequency band difference corresponds to one frequency band difference absolute value, and the frequency band difference absolute value is an absolute value of the frequency band difference; and determining whether the plurality of harmonics has the target harmonic based on the plurality of frequency band difference absolute values.

[0036] In a preferred embodiment, the step of determining whether the multiple harmonics include a target harmonic based on the multiple frequency band difference absolute values ​​includes the steps of determining whether the multiple frequency band difference absolute values ​​include a target frequency band difference absolute value, where the target frequency band difference absolute value is a frequency band difference absolute value within a predetermined frequency band range, and, if the target frequency band difference absolute value exists, determining that the harmonic corresponding to the target frequency band difference absolute value is the target harmonic.

[0037] As described above, a target frequency band corresponding to a target signal is determined, and 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 which harmonic is the harmonic that causes interference to the target signal is determined based on the absolute value of the frequency band difference.

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

[0039] In step S201, a target operating clock of the processor is determined. In step S202, determine a plurality of harmonic clocks corresponding to a plurality of harmonics, where one harmonic corresponds to one harmonic clock, and the harmonic clock is a clock of a corresponding harmonic; In step S203, it is determined whether or not the multiple harmonics include a target harmonic based on the target operating clock and the multiple harmonic clocks.

[0040] More specifically, it is determined whether or not there is a clock among the multiple harmonic clocks that affects the target operating clock, and if there are one or more harmonic clocks among the multiple harmonic clocks that affect the target operating clock, the harmonic corresponding to the harmonic clock is determined to be the target harmonic.

[0041] In the method according to the present disclosure, after determining the target signal, the method further includes broadcasting the target signal to timing controllers corresponding to the multiple chips and devices, whereby the other chips and timing controllers receive the communication signal sent from the CPU and used by the device through the broadcast information.

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

[0043] As described above, in the method disclosed herein, by adjusting the operating clock of the target harmonic, there is a large difference between the operating clock of the harmonic and the operating clock of the target signal, and thus the interference of the target harmonic with the communication signal can be reduced; meanwhile, the spread spectrum of the target harmonic can be adjusted, and by spreading the spread spectrum, the energy of the target harmonic can be distributed within a range, and the interference of the target harmonic with the target signal can be reduced.

[0044] The above harmonic parameter adjustment method disclosed in the present disclosure can solve the EMI problem, and at the same time, the method has the advantages of low cost, high flexibility and high scalability, and can provide a unified solution based on algorithms, which is easy to apply to various items.
