论文摘要
最近有关于使用毫米波（MMWave）收发器启用带内整束操作的著作。这些作品仅基于通过多输入多输出（MIMO）预编码和组合在收发器的发射器和接收器之间创建足够的隔离。在这项工作中，我们提出了通过模拟自我干扰取消（A-SIC）来补充这些波束形成策略的建议。通过利用A-SIC，取消了一部分自我干扰，而无需进行光束形成，从而可以使用更最佳的波束成形策略用于为用户提供服务。我们使用仿真来证明，即使有有限的分辨率A-SIC溶液，总和频谱效率也有显着的收益。有了一点点的A-SIC分辨率，存在对仅波束形成设计的改进。通过8位A-SIC分辨率，我们的设计几乎接近了理想的全双工操作。据我们所知，这是第一个将波束形成和A-SIC结合起来的MMWave全双工设计，以实现频段的同时传输和接收。
There have been recent works on enabling in-band full-duplex operation using millimeter-wave (mmWave) transceivers. These works are based solely on creating sufficient isolation between a transceiver's transmitter and receiver via multiple-input multiple-output (MIMO) precoding and combining. In this work, we propose supplementing these beamforming strategies with analog self-interference cancellation (A-SIC). By leveraging A-SIC, a portion of the self-interference is cancelled without the need for beamforming, allowing for more optimal beamforming strategies to be used in serving users. We use simulation to demonstrate that even with finite resolution A-SIC solutions, there are significant gains to be had in sum spectral efficiency. With a single bit of A-SIC resolution, improvements over a beamforming-only design are present. With 8 bits of A-SIC resolution, our design nearly approaches that of ideal full-duplex operation. To the best of our knowledge, this is the first mmWave full-duplex design that combines both beamforming and A-SIC to achieve simultaneous transmission and reception in-band.
