Then, one scanning frequency can be selected from the M scanning frequencies as the second scanning frequency, and then the first scanning frequency is switched to the second scanning frequency. scanning frequency. Optionally, the second scanning frequency may be the one closest to the first scanning frequency among the M scanning frequencies.

Further optionally, in the above step 102, before switching the first scanning frequency to the second scanning frequency, the following steps may also be included:

Determine the working power corresponding to the interfering radio frequency channel, and execute the step of switching the first scanning frequency to a second scanning frequency when the working power is greater than a preset working power threshold.

Among them, the strength of interference corresponding to the interfering radio frequency channel is determined by the working power of the corresponding hardware. Furthermore, if the working power is high, it means that the interference is large, and if the working power is small, the interference is small. Furthermore, the preset working power threshold can be set in advance. , when the working power is greater than the preset working power threshold, perform the step of switching the first scanning frequency to the second scanning frequency, and when the working power is less than or equal to the preset working power threshold, do not perform the step of switching the Describe the step of switching from the first scanning frequency to the second scanning frequency.

When the RF works at a frequency other than 1, the scanning frequency remains at frequency A. In this way, cost can be saved and user experience can be improved.

When there is no intersection with the first preset interference frequency point set, the first scanning frequency is maintained. In this way, when the display screen OSC of the electronic device is working, if it is subjected to RF interference, the scanning frequency of the display screen OSC can be switched. It reduces the interference between the OSC of the display screen and the RF radio frequency, improves the communication quality of the user, and has the advantage of high user experience.

203. When there is no intersection between the radio frequency band and the first preset interference frequency point set, maintain the first scanning frequency.

Wherein, for the specific description of the above steps 201 to 203, reference may be made to the anti-jamming method of the electronic device described in FIG. 1 above, which will not be repeated here.

204. When the interference signal corresponding to the radio frequency band does not exist, switch the second scanning frequency to the first scanning frequency.

Wherein, if the interference signal corresponding to the radio frequency band does not exist, it means that the original interference has disappeared and will not cause interference to communication, and further, the second scanning frequency may be switched to the first scanning frequency.

It can be seen that through the embodiment of the present application, when the display screen OSC of the electronic device is working at the first scanning frequency, the radio frequency band of the registered channel is obtained through the modem MODEM of the electronic device, and the first frequency corresponding to the first scanning frequency in the radio frequency band is When there is an intersection between the preset interference frequency point sets, the first scanning frequency is switched to the second scanning frequency, and there is no intersection between the second preset interference frequency point set corresponding to the second scanning frequency and the radio frequency band.
