摘要
面向卫星通信与导航(SCAN)系统多样复杂的应用场景,下一代多址接入(NGMA)技术可以提供更高的通信速率、更多的接入数量和更广的覆盖面积.面向SCAN系统,对基于多功能NGMA、基于多资源NGMA和基于多技术NGMA展开研究,分析了现有的NGMA技术对SCAN系统的性能增益.最后,总结SCAN-NGMA面临的挑战,展望了未来发展的方向,为SCAN-NGMA架构的进一步演进提供了参考依据.
Abstract
In the context of diverse and intricate application scenarios within satellite communication and navigation(SCAN)systems,next gen-eration multiple access(NGMA)technology offers the potential for increased communication rates,expanded access capacity,and broader cov-erage.It focuses on investigating the application of multi-function-based NGMA,multi-resource-based NGMA,and multi-technology-based NGMA within the SCAN system.It also analyzes the performance enhancements that existing NGMA technology can bring to the SCAN sys-tem.Furthermore,this paper concludes by summarizing the challenges inherent in SCAN-NGMA system.It also looks ahead to the future de-velopment direction,providing valuable insights that serve as a reference for the ongoing evolution of SCAN-NGMA architecture.
