本文首次提出了一种在慢瑞利衰落信道下的双信源非对称Turbo编码协作空间调制（SM）方案。在任何编码协作通信中，交织器在减轻无线信道的恶劣影响方面起着至关重要的作用。因此，码匹配交织器（CMI）是有效地使用在所提出的设计。仿真结果表明，在相同条件下，该编码协作通信系统的误比特率性能优于非对称Turbo编码非协作通信系统。由于在目的节点处的联合非对称Turbo解码，这种突出的性能改善已经成为可能。此外，为了检验所提出的方案的有效性，我们还开发了一种基于垂直贝尔实验室分层空时（VBLAST）的两源非对称Turbo编码合作方案，将CMI作为合适的基准。据观察，所提出的方案采用SM具有更好的BER性能比VBLAST方案在相同的条件下。
This paper proposes, for the first time, a two-source asymmetric turbo-coded-cooperative spatial modulation (SM) scheme over the slow Rayleigh fading channel. As in any coded cooperative communication, the interleaver plays a vital role in mitigating the harsh effect of the wireless channel. Therefore, the code matched interleaver (CMI) is effectively used in the proposed design. The simulated results reveal that the bit error rate (BER) performance of the proposed coded cooperative communication system outperforms the asymmetric turbo-coded non-cooperative scheme under identical conditions. This prominent performance improvement has been made possible due to the joint asymmetric turbo decoding at the destination node. Furthermore, to check the effectiveness of the proposed scheme, we have also developed a two-source asymmetric turbo-coded cooperative scheme based on the vertical bell labs layered space-time (VBLAST), incorporating the CMI as the suitable benchmark. It is observed that the proposed scheme employing SM has a better BER performance than the VBLAST scheme under identical conditions.
