在准静态瑞利衰落信道下，提出了一种基于两个RS码嵌套构造的Reed-所罗门编码协作空间调制(RSCC-SM)方案。在该结构中，中继节点采用连续根数较多的RS码，源节点采用连续根数较少的RS码。在中继节点具有过多根的RS码提供了一些额外的冗余。如果在目的节点对源和中继RS码进行联合译码，将获得增强的误比特率(BER)性能。为此，作者提出了基于朴素方法和智能方法两种不同的RS联合译码方法。蒙特卡罗仿真结果表明，在相同的条件下，采用SMART方法的RSCC-SM方案不仅优于相应的编码非协作方案，而且优于采用朴素方法的RSCC-SM方案。
This paper proposes the Reed-Solomon coded cooperative spatial modulation (RSCC-SM) scheme based on nested construction of two Reed-Solomon (RS) codes over quasi-static Rayleigh fading channel. In this construction, the RS code with larger number of consecutive roots is employed at the relay node while the RS code with less number of consecutive roots is employed at the source node. The RS code with excessive roots at the relay node offers some extra redundancy. The enhanced bit error rate (BER) performance will be obtained if source and relay RS codes are jointly decoded at the destination node. Therefore, the authors propose the joint RS decoding based on two different approaches known as naive approach and smart approach. Monte Carlo simulated results reveal that the proposed RSCC-SM scheme utilizing smart approach not only outperforms its corresponding coded non-cooperative scheme but also outperforms its counterpart RSCC-SM scheme employing naive approach under identical conditions.
