Tradeoff-optimality of D-BLAST

We present coding schemes that achieve the diversity-multiplexing tradeoff for Rayleigh fading channels with one or two receive antennas and arbitrary number of transmit antennas. Codes designed for a parallel channel are the key constituents along with the D-BLAST architecture. We show that the joint ML receiver for D-BLAST outperforms the traditional MMSE with successive cancellation receiver.
