摘要
航空短波数据链是民用航空通信系统不可或缺的通信手段之一。针对短波资源有限、传输速率低的特点,提出了航空短波数据链动态TDMA协议,引入短波微时隙的使用,进一步提高信道利用效率,增加了系统容量,满足短波业务实时变化的需求。设计了航空短波数据链系统的仿真场景,分析了动态TDMA协议给航空短波通信系统带来的性能提升。仿真结果表明,设计的动态TDMA协议可以满足数据链的应用需求。
The aviation HF data link is one of the indispensable means of communication for civil aviation communication systems.In view of the limited HF resources and the low transmission rate,this paper proposes a dynamic TDMA protocol for aviation HF data link which introduces the use of micro time slots that adaptively allocate HF channel resources,and improves the channel utilization efficiency,increases the system capacity,and satisfies the demand for HF service changes in real time.This paper designs the simulation scenario of the aviation HF data link system,and analyzes the performance enhancement of the aviation HF communication system brought by the dynamic TDMA protocol.Simulation results show that the designed dynamic TDMA protocol can meet the application requirements of the data link.
