提出了一种基于Kronecker积（KP）构造的分布式Reed-Muller编码空间调制（DRMC-SM）方案。这种特殊的结构使得经典的Reed-Muller（RM）码能够沿沿着源节点和中继节点有效地分布。所提出的DRMC-SM方案不仅提供了比特错误率（BER）性能的弹性，而且由于空间调制（SM）所灌输的额外天线索引传输而提高了频谱效率。KP建设的有用性，在经典的Plotkin（CP）建设的编码合作进行了分析，并没有纳入SM。在中继节点采用一个有效的标准来选择最佳比特，最终导致更好的重量分布的相互构造（源和中继）RM码。数值结果表明，在7 × 10−7的误码率（BER）下，KP结构的信噪比（SNR）比CP结构高1 dB。此外，所提出的DRMC-SM方案优于其非协作Reed-Muller编码空间调制方案以及分布式Turbo编码空间调制方案。由于路径分集、中继节点处的比特的有效选择以及目的地节点处采用的联合软输入软输出（SISO）RM解码，SNR的这种显著增益是明显的。
This paper proposes distributed Reed-Muller coded spatial modulation (DRMC-SM) scheme based on Kronecker product (KP) construction. This special construction enabled an effective distribution of classical Reed-Muller (RM) code along source and relay nodes. The proposed DRMC-SM scheme not only offers resilience in bit error rate (BER) performance but also enhances the spectral efficiency due to additional antenna index transmission inculcated by spatial modulation (SM). The usefulness of KP construction over classical Plotkin (CP) construction in coded-cooperation is analysed with and without incorporating SM. An efficient criteria for selecting the optimum bits is adopted at relay node which eventually results in better weight distribution of the mutually constructed (source and relay) RM code. The numerical results show that proposed KP construction outperforms CP construction by 1 dB in signal to noise ratio (SNR) at bit error rate (BER) of 7 × 10−7 . Moreover, the proposed DRMC-SM scheme outperforms its non-cooperative Reed-Muller coded spatial modulation scheme as well as distributed turbo coded spatial modulation scheme. This prominent gain in SNR is evident due to the path diversity, efficient.selection of bits at the relay node and joint soft-in-soft-out (SISO) RM decoding employed at the destination node.
