Abstract: A method of operating a wireless communication apparatus including an antenna array including a plurality of sub-arrays includes sweeping a receiving beam formed in each of the sub-arrays such that the receiving beam has a plurality of receiving beam patterns at a respective plurality of sweeping positions, and receiving a signal through the antenna array at each of the sweeping positions, generating base channel matrix information including channel matrices corresponding to the receiving beam patterns for each of the sub-arrays, based on the signal, performing a digital sweeping operation on at least one group combination, which is determined using the base channel matrix information, and generating supplemental channel matrix information, and selecting a receiving beam pattern of the antenna array using the base channel matrix information and the supplemental channel matrix information.
