<p>A method for determining a number of uncorrelated transmission channels in a multiple-input-multiple-output transmission system determines the transmission coefficients h 11 ,h 12 ,..., hΝΜof a transmission matrix H of the MIMO system and determines the number N of eigenvalues of the transmission matrix H. The number of uncorrelated transmission channels is determined by a rank k of the transmission matrix H, for which a quotientγ(k);γ(k)' between the sum of the k biggest eigenvalues and at least the next smaller eigenvalue of all N—k smaller eigenvalues is below a threshold valueρTh .</p> |
