Unmanned Aerial Vehicle (UAV) relay communication is an important technical scheme for long range point-to-point wireless communications. To improve the reliability of transmission link for the UAV relay communication system, a novel UAV relay transmission scheme is proposed based on space-time block coding. According to the criterion of maximizing the average mutual information of the dual-hop link of the UAV relaying communication system, an optimal path planning method for the UAV relay communication system is presented. The outage probability and ergodic capacity of the UAV relay communication system are derived using Finite-Mixture with Expectation-Maximization (FM-EM) algorithm. The computer simulation results indicate that the proposed scheme is superior to the traditional Single-Input Single-Output (SISO) UAV relay communication scheme.
