The use of Unmanned Aerial Vehicles (UAV) is increasing day by day to enhance the wireless communication networks because of its mobile and flexible nature. They act as both the relay nodes and as a flying base station resulting in extension of coverage area and enhancing the performance of network. In this following paper, we investigate the performance analysis of UAV enabled two hop mixed α − κ − µ/Rayleigh based network where UAV is acting as decode and forward (DF) relay node between the transmission from base station to multiple users as the direct link between them is blocked. The channel model used from BS to UAV is α − κ − µ fading model and from UAV to multiple users, Rayleigh fading model is used. Closed form expressions of outage probability is derived. Due to the complex nature and to get more detailing of coding gain and diversity order, asymptotic outage probability is also derived at higher signal to noise ratio (SNR) regime.
