Abstract
A communication device for transmitting orthogonal frequency division multiplexed (OFDM) signals in a wireless communication system. The device includes a plurality of antenna elements that transmit the OFDM signals to a receiver over a plurality of transmission channels in the wireless communication system. The device also generates weight coefficients applied to each of the plurality of subcarrier signals, and controls an amplitude and/or phase of the plurality of subcarrier signals as a function of said weight coefficients.
