Abstract
An operating method of a slave node that communicates with a master node in an in-band full duplex (IFD) system may comprise receiving a beacon signal from the master node during a training sequence period; transmitting a first self-interference (SI) training sequence including a first radio frequency (RF)/analog SI training sequence, a first automatic gain control (AGC) sequence, and a first digital SI training sequence to the master node during the training sequence period after the beacon signal is received; calculating a filter factor for canceling an analog SI signal input to the slave node on the basis of the first RF/analog SI training sequence; and canceling the analog SI signal from the first AGC sequence on the basis of the filter factor.
