Distortion minimization for multimedia transmission in NOMA HAP-UAV integrated aerial access networks
文献摘要：
Aerial access networks have been envisioned as a promising 6G solution to enhance the ground communication systems in both coverage and capacity.To better utilize the spectrum and fully explore different channel characteristics,this paper constructs an integrated network compris-ing the High Altitude Platform(HAP)and Unmanned Air Vehicles(UAVs)with the Non-Orthogonal Multiple Access(NOMA)technology.In order to improve the transmission quality of images and videos,a power management scheme is proposed to minimize the distortion of the transmissions from the HAP and UAVs to the terminals.The power control is formulated as a non-convex problem constrained by the maximal transmit power and the minimal terminal rate requirements.The variable substitution and the first-order Tailor's expansion is used to transform it into a sequence of convex problems,which are subsequently solved through the gradient projec-tion method.Simulation demonstrates the signal distortion and error rate improvement achieved by the proposed algorithm.
