Abstract
A reception device receives, by a plurality of antennas, signals in which a plurality of radio signals are superimposed, the reception device including: a weight generation unit that generates a weight for beamforming in order to improve reception quality of a desired signal, which is one of the plurality of the radio signals, on the basis of a reception timing and a frequency of the signals received individually by the antennas; a weight correction unit that performs correction, on the weight, in order to compensate for a Doppler shift between the signals received individually by the antennas on the basis of the frequency of the signals received individually by the antennas; and a combining unit that combines the signals received individually by the antennas using the weight obtained after the correction.
