摘要
短波通信是实现超视距军事通信的重要手段之一,美军标MIL-STD-188-141B定义了第三代短波自动链路建立(3G-ALE)技术体制。高速数据链路协议(HDL)是3G-ALE系统中为一对短波终端或节点之间提供无差错数据传输的自动请求重发(ARQ)协议。详细阐述了短波3GALE系统中的HDL协议,介绍了其原理,分析了其优缺点,提出了改进措施,并将改进措施与原协议在吞吐量上进行了比较,理论分析及仿真结果直观显现了改进措施的有效性。
HF （High-Frequency） communication is one of the important measures for beyond-visiual range military communication. MIL-STD-188-141B defines the 3G HF automatic link and establishes （3G-ALE） technical system. HDL （High-Rate Data Link） protocol is an ARQ protocol in 3G-ALE sys- tem, providing error-free data transfer to a pair of HF terminals or nodes. Meanwhile, HDL procotol in 3 G -ALE system is described in detail, including its principle, advantages and disadvantages, and some sug- gestions for its modification are proposed. In addition, the throughput capacity of between the modified and the original protocal is also compared. Theoretical analysis fectiveness of this modified measure. and simulation results intuitively indicate the el-
