Abstract
The present invention relate to a method of extracting an optimum rank without considering a precoding matrix indicator (PMI) in a multiple-input multiple-output (MIMO) receiver, the method including calculating a correlation matrix from a MIMO channel matrix between a base station antenna and an MIMO receiver antenna; obtaining an eigenvalue from the correlation matrix; calculating channel capacity for each rank on the basis of the obtained eigenvalue; and selecting a rank corresponding to a channel capacity having a maximum value among the calculated channel capacities for each rank as an optimum rank.
