Abstract

In-band full duplex (IBFD) is regarded as one of the most significant technologies for addressing the issue of spectrum scarcity in 5G and beyond systems. In the realization of practical IBFD systems, self-interference, i.e., the interference that the transmitter causes to the collocated receiver, poses a major challenge to antenna designers; it is a prerequisite for applying other self-interference cancellation (SIC) techniques in the analog and digital domains. In this paper, a comprehensive survey on SIC techniques in the antenna/propagation (AP) domain is provided and the pros and cons of each technique are studied. Opportunities and challenges of employing IBFD antennas in future wireless communications networks are discussed.

摘要

带内全双工 (IBFD) 被认为是解决 5G 及未来系统频谱稀缺问题的最关键技术之一。在实际的 IBFD 系统实现中，自干扰，即发射器对同信道接收器造成的干扰，对天线设计师构成了重大挑战；它是在模拟和数字域中应用其他自干扰消除 (SIC) 技术的前提。本文对天线/传播 (AP) 域中的 SIC 技术进行了全面的调查，并研究了每种技术的优缺点。讨论了在未来无线通信网络中采用 IBFD 天线的机会和挑战。
