Query: Performance Analysis of Self-Interference Cancellation in Full-Duplex
  Large-Scale MIMO Systems   This paper presents the performance analysis of the self-interference
cancellation (SIC) methods in full-duplex largescale multiple-input
multiple-output systems. To mitigate selfinterference (SI), we assume that the
full duplex-base station (BS) uses SI-subtraction or spatial suppression.
Analytical and numerical results confirm that the SI-subtraction outperforms
the spatial suppression for SIC in a perfect channel estimation case. It is
also concluded that the uplink and overall ergodic rates performance of the
spatial suppression is respectively better than those of the SI-subtraction in
a imperfect channel estimation case under a given system constraint such as
uplink/downlink sum rates and the total transmit power at the BS.
