岸海短波通信更频策略研究

Research on Frequency Update of Coast-Sea HF Communication

论文针对目前岸海短波通信更频存在的问题,研究了四种可以缓解或解决现有问题的更频策略,分别是特殊时间节点更频、固定时间节点更频、网络重置更频、门限更频。给出了这四种更频策略的定义,详细阐述了每种策略的更频过程。最后,对每种更频策略的优劣作了简要说明。

Aiming at the problem of the frequency-update in coast-sea HF communication, this paper studies four strat- egies, including special time node frequency-update, fixed time node frequency-update, network reset frequency-update, threshold frequency-update, which can solve or alleviate the existing problems. The definition of four strategies frequency- update is given. The frequency process of each strategy is described in detail. Finally, the advantages and disadvantages of each strategy are briefly described.
