“…Due to the height-independent nature of shaping parameters [26], the actual performance in practical scenarios may be affected. The analytical closedform expression of an outage probability is derived in [27] for the UA-NCC system using the Rician fading and a height-independent path-loss exponent for modelling largescale attenuation. The destination node uses selection combining (SC) for the direct signal and the signal coming via the UAV, while the UAV use decode-and-forward (DF) relaying for decoding purposes.…”

“…The destination node uses selection combining (SC) for the direct signal and the signal coming via the UAV, while the UAV use decode-and-forward (DF) relaying for decoding purposes. The height-independent Rician factor does not provide the actual characterization of A2G links [27], therefore the performance deviates from the true one in real-world scenarios. The analysis of the UA-NCC system is considered [9] in a probabilistic channel model where A2G links are assumed either Rayleigh or Rician based on the probability of occurrence of LoS.…”

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.
