Problems solved by technology

[0004] In related technologies, filters are usually added to the radio frequency transmission path to suppress co-channel interference or second harmonic interference similar to the above, but this single-side filter solution still has the problem of insufficient antenna isolation. To completely solve this problem, it is necessary to add additional filters to suppress interference, resulting in increased costs

Abstract

The invention discloses a method for reducing inter-antenna interference, an electronic device and a storage medium, and the method comprises the steps: determining an interference party and an interfered party in a first communication module and a second communication module when monitoring that the first communication module and the second communication module work simultaneously; calculating the maximum transmitting power of the interference party when the signal intensity of the target interference signal at the interfered party is the acquired maximum signal intensity; adjusting the actual transmitting power of the interference party to a value which does not exceed the maximum transmitting power, thus the maximum transmitting power range of the interference party is obtained based on the maximum signal intensity of the target interference signal; the interference of the target interference signal to the interfered party can be effectively controlled within an allowable range by controlling the transmitting power of the interference party; not only is the interference between the antennas of the two communication modules effectively reduced, but also the transmitting power of an interference party and the interference degree of an interfered party can be balanced, the interference between the antennas is reduced, and the transmitting power of the interference party is ensured.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for reducing interference between antennas, an electronic device, and a storage medium. Background technique [0002] At present, with the development of technology, the requirements for information transmission are becoming more and more diverse, and different types of information transmission may require different communication frequency bands. An electronic device may use different communication frequency bands for information transmission, causing same-frequency interference or second harmonic interference between different antennas of the electronic device. [0003] For example, in regional IoT communication scenarios such as smart home and industrial data collection, a long-distance, low-power, and mass-connected wireless communication technology is required for the connection between people and things or between things. It is generally called...
