PURPOSE: A method is provided to reduce a computational complexity for updating a weight in a system having a plurality of antennas. CONSTITUTION: A method comprises a step(S14) of separating the received signal into a desired signal and an interference noise signal; a step(S15,S16) of estimating a correlation matrix having Hermitian and Toeplitz shapes with respect to the desired signal and the interference noise signal, and calculating a learning parameter in the estimated correlation matrix; and a step(S17,S18) of calculating an eigenvalue by using the learning parameter, and updating a weight by using the learning parameter and the eigenvalue.
