In this paper, we consider analog cancelation for full-duplex wireless multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems in multipath self-interference channels, where a full-duplex node is equipped with multiple transmit and receive antennas. For analog cancelation in full-duplex MIMO systems, we propose baseband self-interference signal emulation approaches, where the baseband self-interference signals from all transmit antennas are emulated in the baseband at each receive antenna, and the emulated baseband self-interference signals are upconverted to obtain the emulated radio-frequency (RF) self-interference signals. Numerical results are presented to verify the self-interference suppression performance in MIMO multipath self-interference channels.
