“…Regarding multi-hop relaying, a number of investigations on the impact of CCIs on the performance of the system were conducted. It is assumed that CCIs were subject to Rayleigh fading and the system performance which were evaluated in terms of outage probability, average symbol error probability (ASEP) and ergodic capacity [14,15]. Meanwhile, CCIs were assumed to be subject to Nakagami-m fading channels to compute outage probability, error probability and ergodic capacity which were investigated in [16], and over Nakagami-m fading channels, the performance of CSI in AF multi-hop relaying networks under the impact of CCI was considered [17].…”

Under the impact of co-channel interference (CCI) at two source nodes and the relay, we investigate the performance of dual-hop amplify-and-forward (AF) relaying networks. In terms of energy harvesting, the power-constrained relay first scavenges energy from the received signal and CCI signals then amplifies them and forwards them to the destination. In particular, we provide closed-form expressions for outage probability and bit error ratio (BER) to easily analyse the system performance. In this paper, the impact of distinct interference power level and the number of CCIs are derived. Monte Carlo simulations are used to provide expressions related to outage probability performance. It is confirmed that energy efficiency at the relay can be enhanced due to several advantages of CCI signals which can also prolong the life expectancy of relaying systems.

This paper investigates the performance of -hop ( ≥ 2) amplify-and-forward (AF) relaying systems with both relays and the destination subject to independent and not necessarily identically distributed multiple cochannel interferences (CCIs). Based on a new class of upper bound of the equivalent signal-to-interference ratio (SIR) which is the harmonic mean of the minimum of the first ≥ 0 hop SIRs and the minimum of the remaining − hop SIRs, new approximate closed-form expressions of the outage probability and the ergodic capacity are derived. Furthermore, we derive the asymptotic expression of outage probability which accurately reveals the achievable coding gain and diversity gain. Finally, numerical results validate the correctness of the derived expressions.

“…For example, a dual-hop relay system with multiple relays and a single interferer at each relay was considered in [7], while the effect of multiple interferers at the relay and destination nodes of a DF relay network was considered in [8]. Moreover, the outage probability for dual-hop relay systems in the presence of multiple Rayleigh interferers was considered in [9]- [12].…”

In this paper we investigate the effect of co-channel interference on the performance of multihop transmission systems that employ amplify-and-forward (AF) relays and operate in a Rayleigh fading environment. Using an upper bound for the end-to-end signal-to-interference-and-noise ratio (SINR) which is given by the minimum SINR of all the hops, we derive closed form expressions for the outage probability and the moment generating function (MGF) of the SINR bound. The average symbol error rate of various modulation formats in multihop AF relay systems can then be obtained using the MGF-based approach, whereas closed-form expressions are obtained for the case of binary phase shift keying. The analysis considers relay systems that suffer from the presence of noise and interference as well as interferencelimited and noise-limited systems. The accuracy of the analytical results is verified by computer simulation.Index Terms-Multihop relaying, end-to-end SINR, amplifyand-forward, outage probability, co-channel interference.
