“…On the one hand, as mentioned in many references, using relays can provide extra spatial diversity and expand the coverage of wireless communication systems [21,22]. Recently, the relay-based one-way and two-way cooperative AmBC systems were investigated in [23][24][25][26][27][28][29][30], respectively. In particular, the authors in [23] studied the outage probability and throughput of an energy harvesting enabled decode-and-forward (DF) cognitive relay network over Rayleigh fading channels, where AmBC was utilized as secondary communication.…”

“…The authors in [27] proposed an opportunistic ambient backscatter assisted DF relaying scheme, where the relay can forward signals and perform AmBC operation concurrently. In [28], a dual-hop cooperative AmBC system was considered, where the AmBC technique was used in the first hop. In [29], the secrecy performance and energy efficiency of a relaybased cooperative AmBC system with passive eavesdroppers were investigated.…”

Previous works only focus on the optimization design for the dual-hop cooperative ambient backscatter communication (AmBC) system with single-relay selection. The impact of relay selection on the outage performance of dual-hop cooperative AmBC systems is still missing. Motivated by this, in this paper, we investigate the outage performance of a dual-hop cooperative AmBC system with single-relay selection, where the backscatter link shares the receiver with the cellular link and the harmful direct-link interference (DLI) is mitigated by using successive interference cancellation (SIC). In the system considered, the selected relay has dual functions. One is to forward message for the cellular link, and the other is to act as the radio-frequency (RF) source for the backscatter device (BD). Specifically, after proposing two novel single-relay selection schemes (RSSs), namely reactive RSS and proactive RSS, we derive the closed-form outage probability (OP) expressions for both RSSs, which can be performed in a distributed manner. To gain more insights, the asymptotic OPs at high signal-to-noise ratio (SNR) are explored and the outage performance comparison between the reactive RSS and proactive RSS are also provided. Results show that the proposed reactive RSS is outage-optimal among all possible single-relay selection schemes. The theoretical analysis is validated by Monte Carlo simulations. The results also show that the relay selection scheme, the number of relays, the location of BD, and the reflection coefficient of BD have great impact on the outage performance of cooperative AmBC systems.

“…Despite these advantages of BC, it is appropriate for shortrange communications [3] and cannot meet the requirement of long-range IoT applications. One promising way to extend the communication range is the hybrid paradigm of BC and AC, where the IoT nodes can either modulate and backscatter their own information to the receiver via BC, or transmit information after harvesting enough energy, subject to the energy-causality constraint of each IoT node.…”
