PROBLEM TO BE SOLVED: To provide a method for determining receiver beam forming vectors for a plurality of receivers in a MIMO system. SOLUTION: Each receiver includes a plurality of receiver antennas. A MIMO system also includes a plurality of transmitter antennas. A method includes quantifying properties of channels of the MIMO system in a channel property matrix, including interference among individual channels and performing Cholesky decomposition of the receiver property matrix row-by-row into a lower triangular matrix with unit elements along its diagonal, a diagonal matrix and the Hermitian transpose of the triangular matrix. Performing of Cholesky decomposition includes determining, when performing a step of the Cholesky decomposition for a certain row, that a receiver-beam forming vector associated with the row maximizes the component of the diagonal matrix in the row.
