MF-TDMA和FDMA传输自适应体制下的资源分配
|
摘要
作为卫星通信系统中常用的传输体制,MF-TDMA高效灵活,FDMA稳定可靠,2种体制混合组网后,用户能够根据实际能力来自适应的选择传输体制,极大地提升了系统性能,而如何统一、高效地利用有限频带资源则成为了混合组网的关键技术一。提出了一种资源分配方法,能够同时满足2种不同体制的需求,通过对算法的仿真分析,结果表明该方法能够高效、灵活地分配公共资源,完全满足MF-TDMA和FDMA体制混合组网时不同的资源需求。
As a commonly used transmission system in satellite communication systems,MF-TDMA is highly efficient and flexible,and FDMA is stable and reliable.After the two systems are mixed and networked,users can adaptively select the transmission system based on actual capabilities,which greatly improves system performance.How to uniformly and efficiently use limited-band resources has become a key technology for hybrid networking.This paper proposes a resource allocation method that can meet the requirements of two different systems at the same time.The simulation analysis results of the algorithm show that it can allocate public resource efficiently and flexibly,and completely meet the different resource requirement when the MF-TDMA and FDMA systems are mixed.
