Abstract

PURPOSE:To certainly cancel the interference wave mixed in a main antenna, by performing the modulation of a PN wave (pseudo-noise wave) with respect to the interference wave received by an interference receiving terminal. CONSTITUTION:A main antenna 1 for receiving a desired wave and an auxiliary antenna 2 turned to an interference wave source are provided. The interference wave received by the auxiliary antenna 2 is applied to an adder 3 through a vector modulator 4 and synthesized with the interference wave mixed in the main antenna 1 to negate the interference wave mixed in the main antenna 1. The vector modulator 4 controls the interference wave received by the auxiliary antenna 2 so as to allow the same to become a signal having amplitude equal to that of the interference wave mixed in the main antenna 1 and a phase reverse to that of said interference wave and the modulation of a PN wave is performed.
