1. In a multiple-input multiple-output (MIMO) communication system, a method for processing data for transmission over a multipath MIMO channel, comprising:

  • coding data in accordance with one or more coding schemes to provide coded data;

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

    precoding the modulation symbols based on an equivalent channel response derived based on the estimated response of the MIMO channel and a response of a feed-forward filter of a decision feedback equalizer to provide precoded symbols; and

    preconditioning the precoded symbols based on an estimated response of the MIMO channel to provide preconditioned symbols for transmission over the MIMO channel.
