Claim Text:
1. An apparatus for cancelling a self-interference signal between a transmission antenna and a reception antenna, the apparatus comprising: a first self-interference signal cancellation unit for cancelling a self-interference signal in consideration of a linear channel between the transmission antenna and the reception antenna; a second self-interference signal cancellation unit for cancelling a self-interference signal in consideration of nonlinear channel characteristic or linear characteristic of a radio channel between the transmission antenna and the reception antenna; and a controller for comparing a transmitted signal output from the transmission antenna and a received signal received by the reception antenna to provide a first coefficient to be applied to self-interference signal cancellation of a linear element in the first self-interference signal cancellation unit and a second coefficient to be applied to self-interference signal cancellation of a nonlinear element in the second self-interference signal cancellation unit.
