提出了一种基于多输入多输出（MIMO）双向中继的D2 D通信系统，其中中继采用物理层网络编码（PNC）。蜂窝通信和D2 D通信都发生在相同的频谱中。D2 D通信基于PNC，并且需要联合收发器设计来促进与MIMO信道的PNC映射。在蜂窝通信中还考虑了联合预编码器-解码器方案以减轻干扰，并改善差错性能。在联合预编码器-解码器的设计问题中，考虑了节点的均方误差作为目标函数，干扰门限限制和功率约束也被使用。这些原来是非凸优化问题，我们提出了两个算法在这两个阶段的D2 D和蜂窝通信。在所提出的算法中使用分布式优化方法。我们分析了所提出的算法的收敛性，并与不同的D2 D对位置，干扰约束阈值，和节点处的最大可用功率的系统性能进行了研究。
We propose a multiple-input multiple-output (MIMO) two-way relaying based underlay device-to-device (D2D) communication system, in which relay uses physical layer network coding (PNC). Both cellular and D2D communication take place in the same spectrum. D2D communication is based on PNC, and a joint transceiver design is required to facilitate PNC mapping with MIMO channels. A joint precoder-decoder scheme is also considered in the cellular communication to mitigate interference, and improve the error performance. Mean square errors at nodes are considered as the objective function, and interference threshold limits and power constraints are also used in joint precoder-decoder design problems. These turn out to be non-convex optimization problems, and we propose two algorithms in both phases of D2D and cellular communication. Distributed optimization methods are used in the proposed algorithms. We analyze the convergence of proposed algorithms, and the system performances are investigated with different D2D pair locations, interference constraint thresholds, and maximum available power at nodes.
