Abstract
The present invention relates to a symbol-wise beamforming apparatus and method in an OFDM communication system using multiple antennas. A weight vector calculator calculates a transmit weight vector using a signal received through the multiple antennas as an input on the basis of channel information in the time domain and covariance matrix information about interference and noise and computes a receive weight vector using the calculated transmit weight vector. At least one of the calculated transmit weight vector and receive weight vector is transmitted to a transmission apparatus through a transmitter.
