Abstract

This paper presents the performance analysis of the self-interference\ncancellation (SIC) methods in full-duplex largescale multiple-input\nmultiple-output systems. To mitigate selfinterference (SI), we assume that the\nfull duplex-base station (BS) uses SI-subtraction or spatial suppression.\nAnalytical and numerical results confirm that the SI-subtraction outperforms\nthe spatial suppression for SIC in a perfect channel estimation case. It is\nalso concluded that the uplink and overall ergodic rates performance of the\nspatial suppression is respectively better than those of the SI-subtraction in\na imperfect channel estimation case under a given system constraint such as\nuplink/downlink sum rates and the total transmit power at the BS.\n
