In a multiple-input, multiple-output (MIMO) communication system, a method and apparatus for multi-antenna transmission. In accordance with the preferred embodiment of the present invention a reduced number of transmit weight matrices are fed back to the transmitter. Each transmit weight matrix is then applied to a plurality of subcarriers. Because each transmit weight matrix is applied to more than one subcarrier, the amount of weight matrixs being fed back to the transmitter is greatly reduced.
