Problems solved by technology

[0002] In a multi-antenna scenario, when the Mobile Industry Processor Interface (MIPI) bus used to transmit data works at a fixed frequency, if its frequency division or multiplication frequency falls on the specific operating frequency of the modem, Can cause antenna interference, resulting in poor communication quality
[0003] At present, the interference to the modem can be improved through hardware upgrades, but it will increase the cost, and the improvement effect is limited. Adjusting the MIPI operating frequency of the display screen cannot ensure that the frequency division and multiplication frequency points do not fall on the operating frequency of the modem at all, which affects the display frame. Indicators such as rate and clarity may also have an impact

Abstract

The embodiment of the present application discloses an electromagnetic interference adjustment method and related products, which are applied to electronic equipment, and the electronic equipment includes a display screen and a modem; the method includes: when an uplink data transmission is detected, acquiring the Modem Operating frequency and the current first operating frequency of the mobile processor interface MIPI of the display screen; if it is detected that the difference between the operating frequency of the Modem and the first operating frequency is within a preset range, it is determined that the electronic device Interference; obtaining the first antenna currently enabled by the Modem; querying a preset mapping relationship set to obtain a first interference frequency list corresponding to the first antenna; according to the first interference frequency list and the first working Frequency determining a target antenna; switching the first antenna to the target antenna. In this way, the transmitting antenna can be dynamically switched to reduce or eliminate the interference of the display screen MIPI on the Modem uplink signal, so that the mobile phone can maintain the best communication performance.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an electromagnetic interference adjustment method and related products. Background technique [0002] In a multi-antenna scenario, when the Mobile Industry Processor Interface (MIPI) bus used to transmit data works at a fixed frequency, if its frequency division or multiplication frequency falls on the specific operating frequency of the modem, It will cause antenna interference, resulting in poor communication quality. [0003] At present, the interference to the modem can be improved through hardware upgrades, but it will increase the cost, and the improvement effect is limited. Adjusting the MIPI operating frequency of the display screen cannot ensure that the frequency division and multiplication frequency points do not fall on the operating frequency of the modem at all, which affects the display frame. Metrics such as rate and clarity may also have an impact....
