The paper aims at comparing the respective benefits of STBICM (space-time bit-interleaved coded modulation) and space-time trellis codes (STTC) for a MIMO block fading multipath channel. Giving a general framework for the calculation of the outage probability, we try to point out the best transmit scheme that approaches the closest the outage probability, assuming the most efficient receiver (i.e., disregarding any complexity aspect). We conclude that iteratively decoded STBICM should be used in preference to STTC.
