“…Rayleigh distributions and the interference to noise ratio (INR) at S i and R are respectively denoted as ρ ii and ρ rr . In the state of the art works, the characterization of the residual SI has been modelled either as a random variable that has a constant signal to interference ratio (SIR), i.e., ρ ii = β i ρ i and ρ rr = β r ρ r [51] or a random variable that is scaled with the transmit SNR by a factor 0 ≤ µ ≤ 1 where ρ ii = ρ 1−µ i and ρ rr = ρ 1−µ r , respectively [34], [42], [43], [52]- [55]. In general, these two models are equivalent for analytical derivation by letting µ = 1 − log ρi β i ρ i and µ = 1 − log ρr β r ρ r .…”

Abstract-In this paper, the spatial modulation (SM) technique is employed at the source and relay nodes in a full-duplex twoway relay channel (FD-TWRC) to support spectral-efficient bidirectional communications while guaranteeing a low cost implementation. Maximum likelihood (ML) detectors are employed at each node that is subject to an intrinsic self-loop interference (SI). We first propose a tight upper bound on the average bit error probability (ABEP). Then based on the ABEP upper bound, an asymptotic ABEP expression is derived in the high SNR regime. Exploiting the asymptotic ABEP, an exact SNR threshold for the selection between FD-TWRC-SM and half-duplex (HD)-TWRC-SM is derived in a closed form, which sheds light on when it is beneficial to select the FD (or HD) mode. In addition, the power allocation (PA) among sources and relay is investigated, through which an optimal PA factor in terms of ABEP is obtained. All analytical results derived in this paper are verified by Monte Carlo simulations, from which some new insights are obtained on the performance of FD-TWRC-SM.

“…Under Rayleigh fading, exact outage probability expressions have been derived in [8] with the direct sourcedestination link treated as interference. Such a relaying scheme, where the information is only distilled from the multihop path, will be referred to as the multi-hop DF (MHDF) scheme in the sequel.…”

Abstract-In this work, we evaluate the performance of relay selection over Nakagami-m fading channels in the presence of a cluster of full-duplex decode-and-forward relays with selfinterference. Specifically, we derive the exact cumulative distribution function of the end-to-end signal-to-interference-plus-noise ratio in the presence of a direct source-destination link. When a direct link exists, all dual-hop paths become mutually correlated due to the common direct-link interference. The presented exact results enable the evaluation of the outage performance and system throughput for fixed-rate transmission systems. The theoretical findings are verified by numerical simulations, where the severity of fading effect in the residual self-interference link is also discussed.

“…In [6]- [8], outage performance was studied for the Rayleigh-fading FDR channel with RSI, where closed-form expressions were presented for decode-and-forward (DF) and amplify-and-forward (AF) protocols. Further comprehensive capacity results were reported in [9], and addressed relay power optimization to locate the optimal tradeoff.…”

On the Outage Performance of Full-Duplex Selective Decode-and-Forward Relaying

We evaluate the outage performance in a three-terminal full-duplex relay channel that adopts a selective decodeand-forward protocol, taking relay self-interference into account. Previous work focused on coverage extension scenarios where direct source-destination transmissions are neglected or considered as interference. In this work, we account for the relay self-interference, and exploit the cooperative diversity offered by the independently fading source/relay message replicas that arrive at the destination. We present an approximate, yet accurate, closed-form expression for the end-to-end outage probability that captures their joint effect. With the derived expression in hand, we propose a relay transmit power optimization scheme that only requires the relay knowledge of channel statistics. Finally, we corroborate our analysis with simulations. Index TermsFull-duplex relay, self interference, selective decode-and-forward, cooperative diversity, outage probability.
