Abstract
A multicarrier receiver generates a quantized transmit beamformer matrix ({tilde over (V)}) for each subcarrier of a multicarrier communication channel for use by a multicarrier transmitting station. The multicarrier receiver applies a corrected receiver beamformer matrix ( .sup.H) to received subcarriers signals generated by signals received from the transmitting station.
