Single-carrier concatenated space-time block coded transmissions over selective-fading channels

We propose single-carrier transmission systems for STBC coded and concatenation of a FEC code with a STBC over ISI fading channels. The proposed receivers rely on iterative successive interference cancellation technique, which avoids the disadvantages of multicarrier systems. Simulation results show that for the STBC only system, the proposed receiver outperforms the OFDM receiver under the power constraint scenario. For the concatenated coding system, the proposed receiver outperforms the OFDM receiver when there is more than one receive antenna.
