NOMA-based energy efficiency optimization method for real-time relay communication network of unmanned aerial vehicle

The invention relates to an energy efficiency optimization method of an unmanned aerial vehicle real-time relay communication network based on NOMA, and belongs to the field of unmanned aerial vehicle communication. The method comprises the following steps: S1, using an unmanned aerial vehicle as a real-time mobile relay, and providing a data issuing service for a plurality of remote area wireless network users in combination with an NOMA technology; and S2, establishing an energy efficiency optimization problem of a real-time relay communication network based on NOMA user scheduling, power distribution and unmanned aerial vehicle trajectory planning on the premise of considering a decoding rule of NOMA, a user service quality demand and unmanned aerial vehicle energy consumption. And S3, decomposing the energy efficiency optimization problem into three independent sub-problems, respectively solving the three independent sub-problems, and iteratively solving the three sub-problems to obtain an effective solut
