Abstract
A beam transmitting device improves performance of a communication channel. The beam transmitting device includes a controller configured to transmit a null data packet (NDP) and receive channel information; and a smoothing circuit configured to smooth a plurality of beamforming vectors in the channel information. The smoothing circuit includes a weight calculator configured to calculate a common phase factor using two adjacent beamforming vectors among the plurality of beamforming vectors, and a moving average filter configured to perform the smoothing using the common phase factor.
