With self-interference cancellation (SIC), a wireless full-duplex terminal is allowed to transmit and receive signal simultaneously in the same frequency band. In this study, the authors first briefly described the impact on the conventional analogue SIC method from the interested signal. To solve this problem, they propose a new practical analogue SIC scheme for full-duplex systems, which is then mathematically analysed in terms of SIC capacity. Simulation results show that the analogue SIC performance obtained by the proposed method outperform the existing analogue SIC method.

全双工系统模拟自干扰消除中衰减器和移相器调整的有效方案

使用自干扰消除（SIC），可以使无线全双工终端在同一频带中同时发送和接收信号。在这项研究中，作者首先简要介绍了感兴趣信号对传统模拟SIC方法的影响。为了解决这个问题，他们提出了一种适用于全双工系统的新型实用模拟SIC方案，然后根据SIC容量对其进行数学分析。仿真结果表明，该方法获得的模拟SIC性能优于现有的模拟SIC方法。
