用数字信号处理器实现的短波自适应选频控制器

A DSP realization of the HF adaptive frequency selection controller

结合短波自适应选频的工作原理，利用ＤＳＰ（数字信号处理）芯片，实现了短波自适应选频的硬件结构和软件，并给出了室内及实际线路的试验结果．多次实际线路试验表明：该控制器能够在预置的频率中选出最佳频道，且符合美国军标ＭＩＬ－ＳＴＤ－１８８－１４１Ａ．

The HF adaptive frequency selection controller is a system to improve the performance of HF communication. In this paper, the working principle of HF adaptive frequency selection is described. The main module of the controller is realized through the DSP (digital signal processing) method, with its hardware construction and software realization method discussed. Finally, some test results obtained in the laboratory and on a real circuit are given. A number of tests have shown that this controller can select the optimal frequency within given frequencies and comforms to the MIL STD 188 141A standard.
