Estimation of UAV to UAV Performance as a Hotspot by Proposed Friss Model on Downlink AF Co-operative NOMA

the advent of unmanned aerial vehicles (UAVs) has brought about a new paradigm of development in different sectors of technology. One such area is the communication industry. Telecommunication operators are finding ways to improve coverage, capacity, and security. One alternative that can be applied to enhance the performance of the Wi-Fi hotspot is unmanned aerial vehicles. In many situations where the distance between a base station and mobile subscribers is very long, it is sometimes difficult to attain good coverage by mobile users. To this end, UAVs can be applied to support the transmission of signals to these users. In this paper, we study the following UAV relay scenarios: fixed-gain amplify-and-forward (AF) relay co-operative, the theoretical path loss by Friss method, use of QPSK modulation and outage probability. Simulation results demonstrate improvements in performance compared to the theoretical acknowledged type.
