Abstract

The embodiment of the invention provides an offshore unmanned aerial vehicle communication coverage optimization method and system, and the method comprises the steps: dividing a target sea area corresponding to an unmanned aerial vehicle into a plurality of areas, wherein each area comprises the same number of user terminals; performing power iteration on any region based on a non-orthogonal multiple access technology to enable the reachable data communication rates of the user terminals to be equal so as to obtain an optimal fair user rate in any region; and based on the optimal fair user rate, allocating the signal transceiving power of the unmanned aerial vehicle in each region to enable the reachable data communication rates of all user terminals in the target sea area to be equal. Under the condition of traditional average power distribution, the fairness problem in the NOMA system is more obvious than that in an OMA system (an orthogonal multiple access system), the fairness problem is effectively solved through a new power distribution scheme, and the communication quality of a far-end user with a poorer channel is effectively improved.

Description

technical field [0001] The invention relates to the technical field of coverage optimization in wireless communication, in particular to a method and system for optimizing communication coverage of a marine drone. Background technique [0002] In recent years, with the rapid development of maritime activities such as maritime tourism, marine industry and fishery, my country's marine economy is very active, and the demand for marine communication services from maritime user terminals is also increasing. Passengers and crew members on board need broadband Internet technology to meet their entertainment and communication needs. Industries such as marine fishing and resource mining need to use broadband communication to complete information management, upload data, and time-frequency monitoring. The existing maritime communication system mainly includes satellite communication and shore-based communication. The high delay and low rate of satellite communication are difficult t...
