Enabling Full-Duplex MIMO Communication Exploiting Array Antenna Arrangement

This paper presents the developed in-band full-duplex testbed and its performance. The testbed uses two linear array antennas in an end-fire arrangement, which is convenient to suppress the self-interference by transmitting beamforming. The experimental results demonstrate the proposed testbed realizes the interference suppression by about 90 dB even with the normal and feasible transceiver configuration.
