METHOD AND SYSTEM FOR SUPPRESSING INTERFERENCE IN MOBILE DEVICE Russian patent published in 2015 - IPC H04B1/10 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to telecommunication technologies and can be used to suppress noise, i.e. electromagnetic interference. The method of suppressing noise, directed to a main antenna in a mobile device, via noise signal compensation, comprises selecting a place to mount an auxiliary antenna, which is configured to capture a noise signal in the same degree as the main antenna, in the immediate vicinity of the main antenna, selecting the size and type of the auxiliary antenna such that the difference in receiving external signals of the main antenna and the auxiliary antenna at the operating frequency is not greater than 10 dB, matching the auxiliary antenna to receive the noise signal without receiving the main signal, wherein the main antenna is matched with the transmission line using a first transimpedance amplifier, the output of which is connected with the first input of an adder, the auxiliary antenna is matched to receive the noise signal with a second transimpedance amplifier, the output of which is connected to the input of a phase changer, and the output of the phase changer is connected to the second input of the adder.

EFFECT: high sensitivity of reception, miniaturisation.
