Abstract

The invention provides a device for reducing mutual interference between wireless radio frequency modules. The device comprises a first antenna module, a first memory module, a first radio frequency module, a second antenna module, a second radio frequency module and a common module, wherein the first antenna module comprises a first antenna unit and a first adjustment unit; the second antenna module comprises a second antenna unit; and the common module is used for storing the states of the first radio frequency module and the second radio frequency module. By the first adjustment unit added during antenna design, corresponding first adjustment unit parameters are tuned out in advance according to known terminal frequency band information when the first radio frequency module and the second radio frequency module simultaneously work; and the isolation degree between the first antenna unit and the second antenna unit is maximized as much as possible, so that the mutual interference degree between the first radio frequency module and the second radio frequency module is reduced.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a device and an implementation method for reducing mutual interference between wireless radio frequency modules. Background technique [0002] With the development of mobile communication systems, the functions of mobile terminals are becoming more and more powerful, and the design of mobile terminals is becoming more and more complex. In addition to the normal modem modules that meet voice and data services, mobile terminals must also be used for wireless networks. The WIFI (Wireless Fidelity) module and the GNSS (Global Navigation Satellite System, global navigation satellite system) module used for positioning have basically become standard configurations of mobile terminals. In many application scenarios, these different wireless systems need to work at the same time, which will inevitably cause mutual crosstalk, which will seriously affect the normal operation or performance...
