Abstract:
A MIMO communication method for performing MIMO communication between a base station including a plurality of antennas, and a plurality of terminals accommodated in the base station. The method includes, in the base station, dividing the plurality of terminals into a first and a second group, and assigning orthogonal codes with each other to the respective groups, spreading transmission data to the plurality of terminals with the assigned codes, multiplying data obtained by the spreading by a predetermined pre-coding matrix, obtaining a channel matrix representing channels between the plurality of antennas and the plurality of terminals, multiplying data obtained by the multiplying by the pre-coding matrix by a complex conjugate matrix of the channel matrix, and transmitting data obtained by the multiplying by the complex conjugate matrix from the plurality of antennas.

Claim (Index 2):
The MIMO communication method according to  claim 1 ,\n wherein when a square matrix having the number of terminals in each group as an order is set to a submatrix in a diagonal part of an auto-correlation matrix of the channel matrix, the pre-coding matrix is a block diagonal matrix including the inverse matrices of the submatrices as diagonal parts, and non-diagonal parts set to zero.
