摘要

针对海上作业区域通信资源匮乏的问题，提出了一种基于非正交多址接入（non-orthogonal multiple access，NOMA）的双无人船海上辅助通信物联网系统模型。该模型通过联合优化用户通信调度与传输功率，最大化系统吞吐量。仿真结果表明，与正交多址接入（OMA）技术相比，基于NOMA的双无人船物联网系统具有更高的吞吐量，并通过部署具备低成本、按需配置特点的无人船，为海上风电机组维修人员提供必要的通信保障。同时，引入NOMA技术可提升频谱资源利用率，有望突破海上频谱稀缺的瓶颈。

Abstract

To address the issue of limited communication resources in maritime operation areas

a maritime-assisted Internet of things (IoT) system model based on non-orthogonal multiple access (NOMA) and supported by dual unmanned surface vehicles (USV) was proposed. In this model

the system throughput was maximized through the joint optimization of user communication scheduling and transmission power. Simulation results demonstrate that

compared with orthogonal multiple access (OMA) technology

the NOMA-based dual-USV IoT system achieves higher throughput

and necessary communication support for maintenance personnel on offshore wind turbines is provided through the deployment of USV characterized by low cost and on-demand configurability. Furthermore

the introduction of NOMA technology was intended to enhance spectrum resource utilization

and the bottleneck of scarce spectrum scarcity at sea was expected to be broken through.
