The invention belongs to the technical field of unmanned aerial vehicle communication, and particularly relates to a multi-unmanned aerial vehicle communication rate optimization method. The method comprises the following steps: step 1, establishing a multi-unmanned aerial vehicle communication model; 2, finding out a hovering position by solving a flight-hovering-flight strategy; and step 3, jointly optimizing the trajectory and power of the unmanned aerial vehicle to maximize the channel capacity. Aiming at the problem of calculating the maximum channel capacity by considering factors such as mutual interference and safety distance among the unmanned aerial vehicles when the multiple unmanned aerial vehicles communicate with respective users at the same time and the same frequency, the method comprises the following steps: firstly, converting into a non-convex optimization problem, establishing a multi-unmanned aerial vehicle communication model, and calculating a hovering position by solving a flight-hovering-flight strategy; and finally, solving by using a continuous convex approximation algorithm, and jointly optimizing the trajectory and power of the unmanned aerial vehicle to achieve the maximum channel capacity.
