Performance Detecting System of Short-Wave Line
【摘要】 介绍了一种对一般短波数据传输信道的各种质量进行估价的方法。目的是能及早预报信道质量恶化的征兆,以此作为自动选频的辅助手段。
【Abstract】 An introduction is made of melthod by which all different evaluation of the qualities concerning data transmission in shortwave signal channel for the purpose of early forcasting portents channels\+′qualty exacerbation.To this effect,a supplementary means is found to realize frequence autoselection.
