摘要
在现代高频通信中，为了提高抗干扰与抗截获性能，使用了突发通信模式。在这种通信任式中，一个关键技术是自适应选频技术。本文介绍了突发自适应选频技术的相关内容，提出了一种自适应选频方案，并在基带上用ＴＭＳ３２０Ｃ３０ＤＳＰ成功地实时摸拟了整个选频过程，证明方案有效可行，在自适应选频后选出的最优频率与预期的一致，并得出了一些有价值的结论。
In modern HF communication,burst communication is applied to improve such performances as anti- interference and anti- interception etc.One of the crucial techniques in burst communication is adaptive frequency selection. It this paper,some relevant concepts about this topic are introduced and a feasible project of adaptive frequency selection is proposed. Furthermore,with the application of TMS320C30 DSP,the real-time process of adaptive frequency selection is successfully simulated in baseband,the optimal channel in frequency selection is the same as estimated,and some valueable conclusions are also drawn
