For a turbo coded BLAST (Bell LAbs Space-Time architecture) system with Nt transmit antennas and Nr receive antennas, there is a significant gap between its detection threshold and the capacity in case Nt > Nr. In this paper, we show that by introducing a convolutional interleaver with block delay between the BLAST mapper and the turbo encoder, the threshold can be improved. Near-capacity thresholds...
In this paper, we investigate detection-decoding algorithms for the near-capacity performances of turbo coded MIMO (multiple-input multiple-output) schemes in the fast fading channel. Both the conventional turbo coded MIMO scheme Gamma0 and turbo coded MIMO scheme with interblock memory which is denoted by Gamma are investigated. Gamma is implemented by introducing some delay elements between the...
