Abstract

Abstract : 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.
