摘要

Provided is a configuration capable of high quality transmission of large volumes of data by LOS-MIMO transmission. Provided is a LOS-MIMO demodulation device that comprises: a plurality of reception antennas which receive data; a phase noise estimation unit which calculates first phase noise information and second phase noise information related to phase noise occurring at a transmission antenna and the reception antennas, from each reception signal received by the plurality of reception antennas; a first correction unit which corrects, based on the first phase noise information, the phase of each of the reception signals received by the plurality of reception antennas; a frequency region equalization unit which performs frequency region equalization processing that compensates for distortion due to interference from each of the reception signals received by the plurality of reception antennas; a second correction unit which corrects, based on the second phase noise information, the phase of the signal by which the signal after the frequency region equalization processing is returned to a time region by a discrete inverse Fourier transform; and a decoding processing unit which performs decoding processing of the data after correction.
