Abstract

To provide a device for radio communication using a plurality of antennas, in which: an amplitude/phase adjuster () and an amplitude/phase controller () control the amplitude and the phase of signals input from at least two antennas such that a directivity, allowing a desired signal to be obtained; an amplitude/phase adjuster () and an amplitude/phase controller () control the amplitude and the phase of the signals input from the antennas such that an arrival direction of the desired signal becomes a null point and that a directivity, allowing a signal other than the desired signal to be obtained; a signal synthesizer () combines the signals; a signal synthesizer () combines the signals; and a desired signal generator removes a signal from the signal synthesizer () from a signal from the signal synthesizer ().
