Abstract

The invention relates to an unmanned aerial vehicle relay device and a wireless communication optimization method and system. An unmanned aerial vehicle carries a reconfigurable holographic metasurface as a relay device for communication between a base station and a user, and optimizes the position of the unmanned aerial vehicle, a holographic beam forming matrix and a power distribution scheme in a wireless communication system consisting of the relay device, the base station and the users, so that the data rate of the multi-user communication system is maximized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an unmanned aerial vehicle relay device, a wireless communication optimization method and system. Background technique [0002] Thanks to its high mobility and high flexibility, UAVs (Unmanned Aerial Vehicle, UAV) are widely used in various fields such as military, public and civilian. Among them, the use of UAVs as communication relays has received extensive attention. Specifically, when the direct link between two or more remote users is affected by the environment or the distance is too far to communicate, drones can be deployed to provide wireless connections between remote users, thereby improving the throughput of the system volume and reliability while extending coverage. Compared with traditional static relays, UAV relays are deployed quickly, which makes it more suitable for emergency situations, such as emergency response and rescue operations. ...
