Performance analysis of full-duplex MIMO-SVD-SIC based relay in the presence of channel estimation errors

In this paper, we propose and analyse the performance of the full-duplex multiple-input multiple-output singular value decomposition (FD-MIMO-SVD) based relay with self-interference-cancellation (SIC). The effects of channel estimation errors for the source-to-relay and self-interference channels are considered. The performance of the system is investigated in the presence of additive white Gaussian noise (AWGN) over Rayleigh fading channels. Analytical results are presented for this system by exploiting SVD as a dominant eigenmode transmission for maximizing the signal-to-noise ratio (SNR) of the desired signal, in addition to mitigating the self-interference (SI). Furthermore, exact, closed-form solutions for the signal-to-interference-plus-noise-ratio (SINR) distribution and outage probability are derived and evaluated along with the average symbol error rate (ASER) for M-ary phase-shift keying (MPSK) modulation schemes.
