We consider a two-way relay system where multiantenna sources employ beamforming to communicate bidirectionally via a single-antenna relay with analog network coding over Nakagami-m fading channels. We address the problem of both separate and joint optimization of power allocation and relay location in order to minimize the overall system outage probability. Our results demonstrate that separate optimization of relay location is more significant than that of power allocation to improve the overall system outage performance. We further emphasize that the joint optimization of power allocation and relay location can provide noticeable outage performance improvement over unbalanced per-hop fading conditions and/or nonidentical antenna configurations.

“…For better insights, we simplify the expressions in (8) and (9) to obtain the expression of the outage probability in closedform. Let us define P a /σ 2 =ρ as the SNR with P b /P a and P r /P a as finite constants.…”

“…However, this result is limited for single antenna nodes. The case of relay power optimisation with no power control at the sources is studied under Nakagami-m fading in [20][21][22][23]. For one-way decode-and-forward scheme, the problem of joint optimisation of power (at source and relay nodes) and relay location over Nakagami-m fading channels is investigated in [23].…”

“…In case the sources were not able to mount multiple antennas and only the relay was mounted with multiple antennas, the capacity region was analyzed in [13] for the AF two-way relaying system, with linear processing at the relay. Another scenario occurs when both sources are mounted with multiple antennas while the relay is mounted with a single antenna [14] [15]. In such a case, the average sum rate of two-way relaying was analyzed [14] over Nakagami-m fading channels.…”

This paper investigates the performance of an amplify-and-forward (AF) two-way relaying system with antenna correlation. The system consists of two multiple-antenna sources, which exchange information via the aid of a single-antenna relay. In particular, we derive the exact outage probability expression. Furthermore, we provide a simple, tight closed-form lower bound for the outage probability. Based on the lower bound, we obtain the closed-form asymptotic outage probability and the average symbol error rate expressions at high signal-to-noise ratio (SNR), which reveal the system's diversity order and coding gain with antenna correlation. To investigate the system's throughput performance with antenna correlation, we also derive a closed-form lower bound for the average sum-rate, which is quite tight from medium to high SNR regime. The analytical results readily enable us to obtain insight into the effect of antenna correlation on the system's performance. Extensive Monte Carlo simulations are conducted to verify the analytical results.
