摘　　要：短波信道是复杂的时变信道,电离层的不稳定性和短波频段的拥挤,使短波可用频段很有限。目前电台各功能模式使用的通信频率大多是预先设置的,短波链路的传输时效低,从而影响了短波通信的使用体验。文章提出了一种智能频率选择算法,自动选择最优频点快速建链以及链路维持,用以解决现有技术中频率选择时间长、建链效率低的问题。HF channel is a complex time-varying channel,and because of the instability of ionosphere and the congestion of HF frequency band,the available HF frequency band is very limited.At present,the communication frequencies used by each functional mode of the radio are mostly preset,and transmission efficiency of HF link is very low,so the use experience of HF communication is not very well.This paper introduces an intelligent frequency selection algorithm,which can select the optimal frequency automatically for fast link establishment and link maintenance,so the problems of long frequency selection time and low link establishment efficiency in current techniques can be solved.

关 键 词：短波信道 频率选择 快速建链
