ABSTRACT:
An interference signal suppressor includes two antennas for receiving desired signals and interference signals, a first adder circuit in which the output signals of two antennas are added to each other, a subtractor circuit in which the output signal of two antennas are subtracted to each other, a signal generating circuit for producing an opposite phase signal with that of the interference signal provided from the first adder circuit and the opposite phase signal are added to each other and a controlling circuit for adjusting the amplitude and the phase of the opposite phase signal to suppress the interference signal.
