An antenna diversity receiver includes a plurality of antennas (1, 2), a plurality of demodulating devices (F1 to FN) prepared per path, to which reception signals received by the plurality of antennas and coming from a plurality of paths are inputted, a synthesizing unit (14) synthesizing demodulated results of the reception signals with respect to the plurality of paths, which are outputted from the plurality of demodulating devices (F1 to FN), and a correlation calculating unit (15) calculating a correlation between the antennas that are common between the plurality of paths, and each of the demodulating devices (F1 to FN) has a plurality of demodulating units (5, 6) outputting demodulation signals (V1, V2) obtained by executing a demodulating process of the reception signals corresponding to the respective antennas, a path weight calculating unit (20) calculating a path weight representing a reception level ratio in the demodulating device by using a value obtained at a stage of the demodulating process by each of the demodulating units, and an output unit (13) outputting, to the synthesizing unit (14), as a result of the demodulation, a result of synthesizing the demodulation signals (V1, V2 of the respective demodulating units, which are multiplied by the synthesization coefficient using the correlation and by the path weight. |
