ABSTRACT:
A system for communicating through a multicarrier communication channel estimates a channel transfer function Hnm(K) each of a plurality of subcarriers of a multicarrier communication channel from received training signals. The system also estimates a spatial correlation matrix Rnn(k) for each subcarrier from noise and interference samples obtained during the reception of the training signals through two or more receive-signal paths. Receiver and transmitter beamformer weights may be generated for the subcarriers using the channel transfer function Hnm(k) and the spatial correlation matrices Rnn(k) for use in subsequent communication through the channel.
