Abstract

Disclosed are a method and apparatus for canceling self-interference signals in a communication system. A first communication node includes a signal transmission unit configured to generate a first RF signal, an antenna module configured to transmit the first RF signal generated by the signal transmission unit and receive a second RF signal from a second communication node, a signal reception unit configured to process the second RF signal and a self-interference signal caused by the first RF signal, and an SIC circuit configured to cancel the self-interference signal. The SIC circuit includes a DSIC circuit for canceling the self-interference signal in a digital domain and an ASIC circuit and an HSIC circuit for canceling the self-interference signal in an analog domain. Accordingly, the performance of the communication system may be enhanced.
