ABSTRACT:
A method is provided for obtaining a reference signal for suppressing an interfering signal received by a radio receiver system. The radio receiver system receives the interfering signal on an antenna along with a signal of interest. An electrically conducting structure on which is present an interfering signal corresponding to the interfering signal present on the antenna and close to the antenna is selected and the interfering signal present on the conducting surface is sampled to obtain a reference signal. The reference signal is provided to an interference cancellation system which generates a cancellation signal used to suppress the interfering signal received by the radio receiver system.
