本文介绍了三种用于全双工无线链路的射频自干扰减少技术，这些技术专门针对紧凑型无线电中的集成。具体而言，提出了一种自干扰消除前端、双极化天线和电平衡双工器。每种技术在实现密度、自干扰抑制、带宽和灵活性方面都具有特定的优势。根据它们的特性，它们可以在不同的下一代全双工应用和标准中采用。所有概念均经过原型设计，并在超过 10MHz 的带宽上实现至少 45dB 的自干扰降低。
This paper describes three RF self-interference reduction techniques for full-duplex wireless links, which specifically target integration in compact radios. Concretely, a self-interference cancelling front-end, a dual-polarized antenna, and an electrical balance duplexer are proposed. Each technique offers specific benefits in terms of implementation density, self-interference rejection, bandwidth and flexibility. Depending on their characteristics, they can be adopted in different next-generation full-duplex applications and standards. All concepts are prototyped, and achieve at least 45dB of self-interference reduction over more than 10MHz bandwidth.
