1. A method of beamforming, comprising:
- generating a beamforming matrix, comprising;
obtaining a channel matrix of a multiple-input, multiple-output (MIMO) channel between multiple transmitter antennas and at least one receiver antenna;
determining an initial beamforming matrix based on a singular value decomposition of the channel matrix; and
generating, by a transceiver, a final beamforming matrix comprising reordering columns of the initial beamforming matrix for at least one sub-carrier of a multi-carrier signal, wherein the reordering of the columns is based on knowledge of encoding of a transmit signal.
