The analogue canceller mitigates the two strongest components of the SI to prevent saturating the receiver. The digital canceller deploys an auxiliary receiver chain to capture the RF-transmitted signal to mitigate the residual multi-path SI signal. As the proposed scheme uses the RF-transmitted signal as reference, the transceiver impairments such as power amplifier non-linearities and phase noise are suppressed along with the SI. Experiments have validated the effectiveness of the proposed scheme on a 20 MHz long-term evolution signal of +20 dBm power. %@ 0013-5194 %T Hybrid SI cancellation for single-antenna full-duplex radios %B Electronics Letters %D November 2017 %V 53 %N 24 %P 1615-1617 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=7fadbhbaj7v3.x-iet-live-01content/journals/10.1049/el.2017.1868 %G EN
