Abstract
Provided is a method and a device for precoding in a wireless communication system. The method for precoding comprises the following steps: generating a first precoding matrix, W, for deciding the transmission power of one transmission antenna from a plurality of transmission antennas as the maximum power per antenna; generating a zero forcing (ZF) precoding matrix, T, which does not influence the transmission antenna having the power which is decided as the maximum power per antenna, based on the (i−1)precoding matrix W(i=2, 3, . . . ); determining α, a constant which has the transmission power of one transmission antenna from the rest of the transmission antennas, which do not have the transmission power as the maximum power per antenna, based on the T; and generating the iprecoding matrix Wbased on the Tand the α.
