Abstract
The polarization beamforming communication apparatus of a base station estimates an azimuth, elevation, and polarization of each of terminals using a reference signal of a terminal received through a plurality of dual polarization antennas, determines a stream to be transmitted based on the azimuth, elevation, and polarization of the terminal, and sends the stream to be transmitted to the terminal through a polarization-matched beam formed in accordance with each of the plurality of dual polarization antennas using the azimuth, elevation, and polarization of the terminal.
