Abstract: A method of operating a wireless communication apparatus, the method comprising: estimating a first channel using a sounding packet received from a base station to obtain an estimated first channel, the sounding packet including a plurality of first streams, generating a diagonal matrix and a beam steering matrix by performing singular value decomposition (SVD) on the estimated first channel, generating state information of a plurality of second channels respectively corresponding to a plurality of second streams generated by applying the beam steering matrix to the plurality of first streams using the diagonal matrix, and transmitting beamforming feedback based on the state information to the base station.
