论文摘要
下一代无线通信的越来越苛刻的目标刺激了有关多安丹娜收发器硬件体系结构和相关智能通信方案的最新研究活动。其中属于整个频带中同时上行链路和下行链路操作的全面双层（FD）多输入多输出（MIMO）体系结构。但是，随着天线元件的数量增加，从FD无线电发射器泄漏到其接收器的干扰信号变得更加严重。在本文中，我们提出了一个统一的FD大型MIMO架构，其中包括模拟和数字传输和接收波束形成（BF），以及模拟和数字SI取消，可以共同优化针对各种性能目标和复杂性要求。提出了拟议体系结构在完全数字和混合模拟和数字BF操作中应用的应用评估结果，并介绍了数据和控制信号的同时通信。结果表明，与各种基准方案相比，针对小型和大量天线的拟议结构可提高光谱效率FD通信，而模拟取消元素则更少。本文以未来FD大规模MIMO通信系统及其有希望的应用的开放挑战和研究方向的列表结束。
The increasingly demanding objectives for next generation wireless communications have spurred recent research activities on multi-antenna transceiver hardware architectures and relevant intelligent communication schemes. Among them belong the Full Duplex (FD) Multiple-Input Multiple-Output (MIMO) architectures, which offer the potential for simultaneous uplink and downlink operations in the entire frequency band. However, as the number of antenna elements increases, the interference signal leaking from the transmitter of the FD radio to its receiver becomes more severe. In this article, we present a unified FD massive MIMO architecture comprising analog and digital transmit and receive BeamForming (BF), as well as analog and digital SI cancellation, which can be jointly optimized for various performance objectives and complexity requirements. Performance evaluation results for applications of the proposed architecture to fully digital and hybrid analog and digital BF operations using recent algorithmic designs, as well as simultaneous communication of data and control signals are presented. It is shown that the proposed architecture, for both small and large numbers of antennas, enables improved spectral efficiency FD communications with fewer analog cancellation elements compared to various benchmark schemes. The article is concluded with a list of open challenges and research directions for future FD massive MIMO communication systems and their promising applications.
