“…The UAV-assisted IRS is considered in [31]- [33], and evaluates the network performance in terms of outage probability, BER, and sumrate by considering height-independent Rician fading, while in practice the Rician factor changes with UAV height. The performance metrics such as outage probability and rate for UAV-assisted CC are analyzed in [34], [35] by considering the hybrid channel (Rayleigh-Nakagami-m) model, where the value of m is fixed with respect of UAV heights that restrict the actual performance. The authors discussed about UAV-assisted device-to-device (D2D) cooperative communication [36], where A2G links are assigned based on the probability of occurrence of LoS and height-independent path-loss exponent is used for large-scale path-loss model.…”

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.
