“…For example, the distributed beamforming and power allocation scheme for FDR was proposed in [6], [7]. The joint beamforming and antenna subset selection scheme for MIMO FDR was considered in [8]. It was shown in [6]- [8] that the FDR, although cannot double the spectral efficiency, does provide considerable performance gain when compared with the traditional HDR.…”

This paper considers the multi-pair full-duplex massive MIMO relaying, where multiple source-destination pairs communicate simultaneously with a common full-duplex amplifyand-forward relay. The low-complexity transceiver design at the relay based on zero-forcing (ZF) processing is presented. The asymptotic expression of the end-to-end signal-to-interferenceplus-noise power (SINR) is derived under the general power scaling scheme. Through the theoretical results, we show that the deployment of very large antenna arrays at the relay has potential to eliminate the effect of echo interference due to the full-duplex operation, if the power scaling scheme is properly selected. Moreover, it is shown that the multi-pair full-duplex relaying outperforms the multi-pair half-duplex relaying in the spectral and energy efficiencies when the number of relay receive/transmit antennas is large.Index Terms-Multi-pair full-duplex relaying, amplify-andforward, very large antenna arrays, asymptotic analysis.

However, the joint impact of antenna correlation and imperfect CSI on the performance of MIMO FD relaying systems is of practical importance and has not been investigated yet.…”

This paper analyzes the performance of multipleinput multiple-output (MIMO) full-duplex (FD) relaying systems, where the source and destination nodes are equipped with single antenna and communicating via a dual-hop amplify-andforward (AF) relay with multiple receive and transmit antennas. The system performance due to practical wireless transmission impairments of spatial fading correlation and imperfect channel state information (CSI) is investigated. At the relay, the loopback self-interference (LI) is mitigated by using receive zero-forcing (ZF) precoding scheme, then steering the signal to the destination by using maximum-ratio transmission (MRT) technique. To this end, new exact closed-form expressions for the outage probability are derived, where the case of arbitrary, exponential, and no correlations are considered. Meanwhile, for a better system performance insights, simpler outage probability lower-bound expressions are also included, through which the acheiveable diversity order of the receive ZF/MRT scheme is shown to be min (NR − 1, NT), where NR and NT are the number of relay receive and transmit antennas, respectively. Numerical results sustained by Monte Carlo simulations show the exactness and tightness of the proposed closed-form exact and lower-bound expressions, respectively. In addition, it is seen that the outage probability performance of FD relaying outperforms that of the conventional half-duplex (HD) relaying at low to medium signalto-noise ratio (SNR). However, at high SNR, the performance of HD relaying outperforms that of the FD relaying. Furthermore, in the presence of channel estimation errors, an outage probability error floor is seen at high SNR. Therefore, for optimum outage performance, hybrid relaying modes is proposed which switches between HD and FD relaying modes.

In this paper, the antenna selection problem is investigated for the relaying system with the base station having massive multiple antennas, where the relay station works in the full duplex mode and the two-way protocol. The antenna selection scheme is optimized by maximizing the minimum of the two signal to noise ratios (SNRs) with each corresponding to the uplink and the downlink traffics. With the optimized antenna selection scheme, the approximate probability density function (PDF) of the received SNR for each receiver is derived. In what follows, both the overall outage probability and the bit error rate are obtained in the analytical expression for the whole massive multi-input multi-output (MIMO) system. Moreover, the asymptotic overall outage probability is derived in an analytical expression with respect to the growing number of the antennas on the massive MIMO base station. Numerical simulations verify the derived analytical results.
