<p>A MU-MIMO system (10), in which a beamformer (11) assigns a plurality of pieces of data (12a-15a) corresponding to a plurality of beamformees (12-15), respectively, to streams (12s-15s), precodes the plurality of pieces of data, and transmits the precoded plurality of pieces of data to the plurality of beamformees (12-15), respectively, is provided with: an assignment means (24) which, in each beamformee group in which channel correlation is high between a plurality of beamformees (12, 13), assigns a data group (1213a) created by grouping a plurality of pieces of data (12a, 13a) corresponding to the plurality of beamformees (12, 13) together to each of streams (12s, 13s); a computing means (25) which precodes the data group (1213a); and a transmission means (21) which transmits the precoded data group (1213a) to the beamformees (12, 13).</p> |
