Abstract:
A RF relay of a full-duplex generates a conversion matrix to belong to a null space of a channel matrix of an interference channel, generates a transmitting signal by converting a received signal using the conversion matrix, and then outputs the transmitting signal to a transmitting antenna. Therefore, an interference signal of an electromagnetic wave level (EM level) that can be generated while the transmitting signal passes through the interference channel can be canceled.
