Abstract:
A method for attenuating interference in a positioning receiver of an electronic device, in which a signal transmitted by satellites of a positioning system is received via a second antenna, and which electronic device further comprises at least a mobile station and a first antenna to be used at least as a transmission antenna of the mobile station, wherein the strength of at least one interference signal generating in the electronic device is determined, a compensation signal corresponding to the strength of the determined interference signal is generated, and said compensation signal is combined to the signal to be received through the second antenna, which combined signal is directed to the positioning receiver, a band pass filtering is performed on said at least one interference signal generating in the electronic device for forming said compensation signal, and adjusting the pass band of said band pass filtering at the frequency band of the signal to be received through the second antenna.
