Self-interference in full-duplex multi-user MIMO channels
journal contribution
posted on 2017-03-01, 09:17 authored by Arman Shojaeifard, Kai-Kit Wong, Marco Di Renzo, Gan Zheng, Khairi Ashour Hamdi, Jie TangWe consider a multi-user multiple-input multipleoutput (MIMO) setup where full-duplex (FD) multi-antenna nodes apply linear beamformers to simultaneously transmit and receive multiple streams over Rician fading channels. The exact first and second positive moments of the residual self-interference (SI), involving the squared norm of a sum of non-identically distributed random variables, are derived in closed-form. The method of moments is hence invoked to provide a Gamma approximation for the residual SI distribution. The proposed
theorem holds under arbitrary linear precoder/decoder design,
number of antennas and streams, and SI cancellation capability.
