提出了一种基于多级构造极化码的空间调制方案，并对其在瑞利衰落和莱斯衰落信道下的性能进行了分析。空间调制表现出的天线索引传输，灌输在所提出的设置增加的频谱效率。此外，在所考虑的多级构造的极化码存在一个并行的内置结构，使我们能够有效地扩展所提出的极化编码空间调制方案的合作场景。为了检查所提出的编码协作空间调制方案的有用性，我们还开发了一个传统的极化编码协作嵌套方案的背景下，空间调制。蒙特卡罗仿真结果表明，在相同条件下，该编码协作空间调制方案的性能优于嵌套编码协作空间调制方案。所提出的编码协作空间调制方案的误比特率性能的提高是由于在目的地节点处的联合连续消除极化解码器的有效部署而成为可能。此外，所提出的编码合作空间调制方案优于其编码非合作对应方案在相同的条件下，如预期的。
A spatial modulation scheme based on the multi-level construction of polar code is proposed and its performance over Rayleigh and Rician fading channels is evaluated. The spatial modulation exhibits antenna index transmission that inculcates an increased spectral efficiency in the proposed setup. Moreover, in the considered multi-level construction of polar code there exists a parallel built-in structure that enabled us to effectively extend the proposed polar coded spatial modulation scheme to cooperative scenarios. In order to check the usefulness of the proposed coded cooperative spatial modulation scheme, we have also developed a conventional polar coded cooperative nested scheme in the context of spatial modulation. Monte Carlo simulated results reveal that the proposed coded cooperative spatial modulation scheme outperforms the nested coded cooperative spatial modulation scheme under an identical conditions. The increased bit-error-rate performance of the proposed coded cooperative spatial modulation scheme is made possible due to effective deployment of the joint successive cancellation polar decoder at the destination node. Moreover, the proposed coded cooperative spatial modulation schemes outperform its coded non-cooperative counterpart schemes under identical conditions, as expected.
