Title: RECEPTION DEVICE, AND TRANSMISSION/RECEPTION DEVICE
Abstract:
[Problem] To provide a reception device and a transmission/reception device which are capable of improving communication quality and curbing power consumption, while reducing the number of antennae and achieving a reduction in size. [Solution] In this reception device, the amplitude and phase of signals inputted from antennae 20, 30 are controlled by amplitude/phase adjustment unit (1) 23 and amplitude/phase control unit (1) 24 so as to achieve a directivity with which a desired signal can be obtained, the amplitude and phase of the signals inputted from the antennae 20, 30 are controlled by amplitude/phase adjustment unit (2) 33 and amplitude/phase control unit (2) 34 using the arrival direction of the desired signal as the null point so as to achieve a directivity with which a signal other than the desired signal can be obtained, the signals are synthesized by signal synthesis unit (1) 25, the signals are synthesized by signal synthesis unit (2) 35, and the signal from signal synthesis unit (2) 35 is removed from the signal from signal synthesis unit (1) 25 by a desired signal generation unit 100.
