论文摘要
全双工毫米波（MMWave）通信表明，通过混合编码和组合来消除自我干扰的前景越来越多。本文提出了一种新型的MMWave多输入多输出（MIMO）设计，用于配置全双工收发器的模拟和数字束式器。我们的设计是第一个整体上考虑模拟波束形成代码簿的关键实际限制，射频频率（RF）链的数量最少，有限的通道知识，光束对准以及有限的接收动态范围。为了防止自我干扰使接收器饱和具有有限动态范围的全双工设备的接收器，我们的设计以每个链条和每RF链为基础解决饱和。数值结果在各种设置中评估了我们的设计，并验证了防止接收器侧饱和度的需求。这些结果和相应的见解是实用全双工MMWave收发器的有用设计参考。
Full-duplex millimeter wave (mmWave) communication has shown increasing promise for self-interference cancellation via hybrid precoding and combining. This paper proposes a novel mmWave multiple-input multiple-output (MIMO) design for configuring the analog and digital beamformers of a full-duplex transceiver. Our design is the first to holistically consider the key practical constraints of analog beamforming codebooks, a minimal number of radio frequency (RF) chains, limited channel knowledge, beam alignment, and a limited receive dynamic range. To prevent self-interference from saturating the receiver of a full-duplex device having limited dynamic range, our design addresses saturation on a per-antenna and per-RF chain basis. Numerical results evaluate our design in a variety of settings and validate the need to prevent receiver-side saturation. These results and the corresponding insights serve as useful design references for practical full-duplex mmWave transceivers.
