频偏对自适应选频系统的影响及估值方法

Frequency offset's effect on HF adaptive frequency selection system and its estimation

讨论了收发频偏对短波自适应选频系统误码性能的影响．介绍一种频偏的估值方法．计算机模拟结果表明，经平滑以后能有效对较大范围的频偏进行估值，并且估值误差较小．

The effect of frequency offset on HF adaptive frequency seleCtion syStem efficiency is analyzed, and a method of frequency offset estimation is given. The results of computer slinuforionindicate that not only can a wide rang of frequency oflsat estimated, but also the error of esttriation is small after a smoothing measure has been taken.
