Method and system for filtering out adjacent frequency band interference

摘要

Provided are a method and a system for filtering out adjacent frequency band interference. The method includes that an RF MEMS switch control module receives a first transmitted coupling signal from a first frequency band RF module and a second received coupling signal from a second frequency band RF module; the RF MEMS switch control module determines whether interference exists between a first frequency band and a second frequency band according to the first transmitted coupling signal and the second received coupling signal; if interference exists, the RF MEMS switch control module filters out the interference by instructing a first frequency band RF MEMS radio frequency reconfigurable antenna working in the first frequency band to change a first antenna structure and/or by instructing a second frequency band RF MEMS radio frequency reconfigurable antenna working in the second frequency band to change a second antenna structure. By means of the disclosure, adjacent frequency bands can co-exist on hardware and mutual interference is effectively avoided.

1. A method for filtering out adjacent frequency band interference, comprising:
receiving, by a Radio Frequency Micro Electro Mechanical System (RF MEMS) switch control module, a first transmitted coupling signal from a first frequency band RF module and a second received coupling signal from a second frequency band RF module, wherein the first frequency band RF module works in a first frequency band and the second frequency band RF module works in a second frequency band; and determining, by the RF MEMS switch control module, whether interference exists between the first frequency band and the second frequency band according to the first transmitted coupling signal and the second received coupling signal; if interference exists, filtering out, by the RF MEMS switch control module, the interference by instructing a first frequency band RF MEMS antenna working in the first frequency band to change a first antenna structure and/or by instructing a second frequency band RF MEMS antenna working in the second frequency band to change a second antenna structure.
