초록
An operation method of an in-band full duplex (IFD) transceiving apparatus including a receiving end, a transmitting end, a digital self-interference cancellation (DSIC) processing unit, and a digital SI cancellation unit may comprise generating, by the DSIC processing unit, signal shaping coefficients for wave shaping of a signal of the transmitting end; generating, by the DSIC processing unit, channel estimation coefficients for cancellation of a self-interference signal in a reception signal of the receiving end; forming, by the DSIC processing unit, a transmission signal based on the signal shaping coefficients; and generating, by the DSIC processing unit, a control signal for cancellation of the self-interference signal in the reception signal based on the channel estimation coefficients.
