摘要
带内全双工技术已经成为提高无线通信系统吞吐量的一种有效方案,然而,该技术中存在的自干扰信号将严重影响带内全双工系统的性能。首先分析了现有的无线带内全双工通信系统中存在的自干扰,并根据干扰的来源将干扰信号分为三类干扰源。然后,分析了现有的一些自干扰抑制技术的抑制效果及影响因素,并据此明确后续研究的方向。
In-band full-duplex（IBFD） technique has become an effective solution for increasing the throughput of wireless communication systems and networks. However,the main affecting factor is the resulting self-interference signal which degrades the IBFD system performance. In this paper,we analyze the self-interference existing in wireless communication IBFD system and classify the interference into three categories according to the source of interference. Then,we present existing research and achievement of different self-interference suppression techniques,including its suppression performance and affecting factors. Finally,we define the future research＇s direction.
