1. A method for transmitting data in a multiple-input multiple-output (MIMO) communication system, comprising:

  • coding data in accordance with one or more coding schemes to provide coded data for a plurality of transmission channels in a MIMO channel;

    modulating the coded data in accordance with one or more modulation schemes to provide a plurality of streams of modulation symbols;

    deriving a pulse-shaping matrix based in part on a first sequence of matrices of eigen-vectors and a second sequence of matrices of singular values corresponding to an estimated channel response matrix of the MIMO channel;

    preconditioning the plurality of modulation symbol streams based on the pulse-shaping matrix to derive a plurality of preconditioned signals; and

    transmitting the plurality of preconditioned signals over the MIMO channel.
