摘要
分析了在通信系统中对通信危害较大的频率漂移问题的产生原因。着重阐述了在监视系统研制过程中针对频率漂移问题所提出的以外向信道为参考基准,通过周期性检测外向信道的频偏值,软件实时修正各用户信道接收频率的解决方法。
In this paper, we analyze the cause of generating frequency drift that has more harm to the VSAT communication system. We describe in detail the solution of periodic detection of outgoing channel frequency deviation for the problem of frequency drift during the development of VSAT monitoring system and all customer channel the receiving frequency modified by using the software.
