摘要
基于短波信道Ｗａｔｅｒｓｏｎ模型，提出了短波跳频系统信道差错率实时监测的一种自适应测量方法。该方法是根据伪错监测统计情况，自适应地选择用于线性外推估值的监测路径来估计差错率，模拟结果分析表明：其短波信道差错率的相对误差为６２．５％。
Based on the Watterson model, this paper proposed an improved method of real time adaptively measuring the channel error rate of frequency hopping for short wave (SW/FH) system.And the method of estimating channel′s error rate that is made use of the detected pseudo errors according to statisic numbers adaptively selected the monitoring path of extrapolation algorithm needed.Using the linear extrapolation algorithm, the simulation result analysis shows that the relative error of evaluation of SW channel′s error rate is 62.5%.
