Abstract: The present invention relates to a device and a method for forming a beam in a multiple antenna system. The method for forming a beam according to the present invention includes: (a) step of receiving a reception signal through a plurality of antennas; (b) step of calculating channel information by decomposing a covariance matrix of the reception signal, and calculating a reception beam forming vector of the reception signal based on the channel information; and (c) step of performing reception beam forming on the reception signal by using the reception beam forming vector. Therefore, the present invention can estimate channel information when receiving an unspecific signal, and can improve reception of a signal by performing the reception beam forming using the reception beam forming vector calculated based on the estimated channel information.
