Abstract: A method by which a communication device using an FDR method estimates a self-interference signal can comprise the steps of: transmitting, in a transmitting end, a pilot signal to which a selected sequence is applied; receiving, in a reception end, a self-interference signal relating to the pilot signal; and estimating a channel of a nonlinear self-interference signal component in a self-interference channel by using a cross correlation characteristic of the selected sequence.
