Full-duplex self-interference mitigation analysis for direct conversion RF nonlinear MIMO channel models with IQ mismatch

Abstract

In this paper, the self-interference mitigation performance of in-band full-duplex multiple-input multiple-output (MIMO) nodes is considered in the context of models for realistic hardware characteristics in which antennas are reused to transmit and receive simultaneously. The use of MIMO indicates a self-interference channel with spatially diverse inputs and outputs. Consequently, there are both MIMO channels for self interference and MIMO channels between the intended transmit array and receive array. Furthermore, physical transceivers suffer from nonlinearities and other nonidealities including IQ mismatch associated with direct conversion RF. Approaches to address self-interference mitigation under this model are presented and performances are detailed.
