Problems solved by technology

[0003] The working frequency band of GPS is 1575.42±1.023MHz. The signal strength sent by the satellite is weak, and it is very susceptible to interference. When there are high-power wireless devices working nearby, they will be interfered and affect their normal work, such as figure 1 As shown, since the cellular communication and GPS communication in the prior art do not work in time-sharing, there will be a certain probability of signal interference between the two
[0004] When the vehicle travels to an area with a weak base station signal (under the viaduct, near high-rise buildings), the power of the cellular communication will be increased according to the adaptive algorithm, which will interfere with the GPS antenna, resulting in reduced positioning accuracy and inaccurate position

Abstract

The invention provides a method and a device for reducing signal mutual interference, electronic equipment and a storage medium. The method for reducing signal mutual interference comprises the following steps: acquiring a synchronization signal output by a GPS module; determining whether the GPS communication is finished or not according to the synchronizing signal output by the GPS module; if the GPS communication is in an end state, turning off the GPS module, and turning on the cellular communication module; and after the cellular communication is finished, closing the cellular communication module, and starting the GPS module. According to the invention, when the GPS module is in the working state, the cellular communication module is in the closed state; and when the cellular communication module is in the working state, the GPS module is in the closed state, so that the time-sharing work of cellular communication and GPS communication can be realized, and the mutual interferencebetween the cellular communication and the GPS communication is effectively reduced. Therefore, the positioning precision of the GPS module can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method, device, electronic equipment and storage medium for reducing signal mutual interference. Background technique [0002] Cellular communication (2G / 3G / 4G) involves many frequency bands. In order to ensure the effectiveness of communication, according to the 3GPP protocol, its transmission power will be adjusted according to the signal strength of nearby base stations. When the signal of nearby base stations is weak At this time, the device will increase its own transmission power. [0003] The working frequency band of GPS is 1575.42±1.023MHz. The signal strength sent by the satellite is weak, and it is very susceptible to interference. When there are high-power wireless devices working nearby, they will be interfered and affect their normal work, such as figure 1 As shown, since the cellular communication and the GPS communication in the prior art do not ...
