摘　　要：自适应跳频是建立在自动信道质量分析基础上的一种技术,能够自动避开被干扰频点,具有较好的灵活性、可靠性和保密性的特点。这里首先介绍了一种自适应跳频系统的模型,阐述了自适应跳频的工作原理和通信过程;然后,对比了最新的几种典型频率自适应算法,给出了不同频率自适应算法的流程图;最后,对几种典型的频率自适应算法的优点和不足之处进行了总结,为实际的工程应用提供了重要的参考。Adaptive Frequency-Hopping, as a technology based on automatic link analysis, could automatically avoid the reliability. This paper describes first jammed channels and is of fairly good flexibil the model of adaptive frequency-hopping system quality ity and and the principle and communication progress of adaptive frequency-hopping; then compares several typical newly-proposed frequency-adaptive algorithms and gives the flow chart of each algorithm in detail. Finally the excellences and disadvantages of each frequency-adaptive algorithm are summarized, thus providing an important reference for the practical engineering applications.
