Abstract:
1. A multi-input multi-output (MIMO) communication system including a transmission station that transmits a plurality of transmission streams from a plurality of transmission antennas and a reception station that receives the transmission streams with a plurality of reception antennas and reproduces the respective transmission streams, the MIMO communication system comprising: multipliers that multiply weighting factors by the respective received transmission streams; and a controller that produces an imbalanced amplitude between a pair of the weighting factors with respect to the respective transmission streams multiplexed to any of the transmission antennas, wherein the controller sets, as the weighting factor, a unitary matrix or a submatrix of the unitary matrix in which a number of rows corresponds to a number of the transmission streams and a number of columns corresponds to a number of the transmission antennas.
