In this paper, we propose a height-dependency shaping parameter (m) and a heightdependency path-loss exponent for modelling small-scale Nakagami-m fading and a large-scale path-loss model for unmanned aerial vehicle (UAV)-assisted network coded cooperation (UA-NCC) system. The statistical parameters such as mean, variance, and probability density function (PDF) of the total noise component (TNC) are analyzed for the proposed system model to achieve the error free communication. We derive spectral efficiency, throughput, and a closed-form outage probability for the UA-NCC system by considering height-dependency shaping parameter (m) and the height-dependency path-loss exponent among ground-to-air (G2A) and air-to-ground (A2G) links, and Rayleigh channel distribution among ground users. The analytical result is validated with simulation results and compared it with the existing work (Rayleigh and Rician fading channel distribution). However, the better performance in the case of the proposed work comes over the existing state-of-the-art (Rayleigh and Rician fading distribution environment) after a UAV height of 10 m.INDEX TERMS UAV, Network coded cooperation, Nakagami-m channel, Rician and Rayleigh channel, Outage probability, Spectral efficiency, Throughput.

“…In [18], outage probability of dual-hop decode-and-forward (DF) relaying scheme was analyzed over mixed Rayleigh and generalized Gamma fading channels. In [19], the authors analyzed the outage probability of opportunistic AF orthogonal frequency-division multiplexing (OFDM) relaying over Nakagami-m fading channel and presented a closed-form outage probability of the proposed system at high signal-to-noise (SNR) regime. In [20], the paper analyzed the performance of two-way amplify-and-forward relaying over Nakagami-m frequency-selective fading channels taking consideration of the multipath spread of the channel.…”

“…The work of [17] and [18] focused on the outage probability of relay-aided networks over Rayleigh channel with AF and DF schemes, respectively, but they did not consider the energy harvesting from an ambient environment. The works of [19,20], and [21] analyzed the performance of two-hop AF relaying over Nakagami-m fading channels, but did not consider on energy harvesting from an ambient environment.…”

This paper investigates the outage performance of an energy-harvesting(EH) relay-aided cooperative network, where the source node transmits information to its destination node with the help of multiple energy-harvesting cooperative nodes. For such a system, we derive an explicit closed-form expression of outage probability over Nakagami-m fading channels, where the on-off EH model is considered. We simulate the explicit closed-form expression of outage probability with different parameters compared with the related Monte Carlo method. It is shown that the simulation results match well with the numerical ones, which demonstrates the correctness of our theoretical analysis. It indicates that to evaluate the system outage performance, our theoretical results can be applied without running the complex Monte Carlo simulation. Via simulations, it is observed that the system outage performance will be improved when natural source EH relays are employed. Besides, more relays, better system performance.
