  • 摘要: 可重构智能超表面(RIS)作为6G移动通信中的潜在关键技术之一,具有低成本、低能耗和易于部署等特点。该文提出将RIS技术引入至海洋无线通信场景中,可使无线传输环境从不可控变为可控。然而,现有的信道模型难以充分揭示RIS使能基站-海面无人船近场通信信号独特的传输机理,信道特性分析方法与建模理论难以在计算准确性与复杂度之间实现平衡。因此,该文通过对RIS使能近场海洋通信中各子信道进行建模,提出空时频多域信号传播机理分析方法,建立RIS使能基站-无人船近场海洋通信参数化统计信道模型,解决现有RIS信道建模方法难以兼顾精度与效率的技术瓶颈问题,提高RIS使能近场海洋通信系统设计过程中的信道模型匹配效率,为我国6G移动通信产业的快速发展提供技术支撑。
