自适应短波系统及其链路建立的分析

Analysis of the adaptive HF radio system and link establishment

以国军标 2 0 77-94等为背景 ,对自适应短波系统的各组成部分加以分析 ,分别对异步与同步呼叫、变长与定长寻址在自动线路建立 ( ALE)中的性能进行了讨论 ,为进一步改进提供了依据 .

The components of the adaptive HF communications systems are examined in this paper. Based on the military standard (e.g. GJB 2077 94), the performances of the asynchronous calling and synchronous calling, variable length addressing and fixed length addressing in Automatic Link Establishment (ALE) are analyzed, and the areas of improvement in techniques and protocols are identified. The methods and strategies for the real time channel evaluation and maintenance and improvement of quality for the link are also discussed.
