A wireless device configured to process Multiple-Input Multiple-Output (MIMO) data streams. The wireless device includes a Singular Value Decompostion (SVD) engine configured to diagonalize a channel matrix into a precoding matrix; an SVD rotation engine configured to phase-rotate the precoding matrix, such that the channel matrix is partially de-diagnalized; and a transmitter configured to transmit a data packet corresponding to the phase-rotated precoding matrix.
