论文摘要
尽管完全双工多个输入多重输出（MIMO）设计中模拟自我干扰癌的硬件复杂性并不一定会随着收发器天线的数量而扩展，从而利用了数百个天线元素的大规模MIMO系统中模拟取消的好处。杂交模拟和数字（A/D）光束架构已被视为一种候选技术，用于实现具有大量天线元件的大量MIMO收发器，但射频频率（RF）链数量较少。在本文中，我们提出了一种新的架构，用于全双工混合体A/D光束收发器，包括多-TAP模拟取消，并减少了TAPS和简单的多路复用器，以在收发器RF链中有效信号路由。利用拟议的收发器体系结构，我们提出了模拟取消的联合设计和A/D光束成形，以最大程度地提高可实现的完整双工速率性能。代表性的毫米波模拟结果证明了提出的体系结构和算法框架的有效性，以同时上行链路和下行链路通信，并降低复杂性模拟性自我解释取消。
Although the hardware complexity of the analog self-interference canceller in full duplex Multiple Input Multiple Output (MIMO) designs does not necessarily scale with the number of transceiver antennas, exploiting the benefits of analog cancellation in massive MIMO systems with hundreds of antenna elements is still quite impractical. Hybrid Analog and Digital (A/D) beamforming architectures have been lately considered as a candidate technology for realizing massive MIMO transceivers with very large number of antenna elements, but with much fewer numbers of Radio Frequency (RF) chains. In this paper, we present a novel architecture for full duplex hybrid A/D beamforming transceivers including multi-tap analog cancellation with reduced number of taps and simple multiplexers for efficient signal routing among the transceiver RF chains. Capitalizing on the proposed transceiver architecture, we present a joint design of analog cancellation and A/D beamforming with the objective to maximize the achievable full duplex rate performance. Representative millimeter wave simulation results demonstrate the effectiveness of the proposed architecture and algorithmic framework for enabling simultaneous uplink and downlink communications with reduced complexity analog self-interference cancellation.
