摘　　要：通过对山西大同雁门关测震台信道特征及误码特征的分析,提出误码产生原因及改善信道的总体思路和试验方法。并对改进后的系统运行情况进行对比分析,发现,雁门关测震台的信道误码减少了。而且同样的改进措施对其他台也有效果,提高了台网系统运行率和地震数据的利用率。Through the analysis on characteristics of signal channel and error code at Seismological Station of Yanmenguan of Datong of Shanxi ,the causes that generate error codes are found. A complete collective thought and test method for improving channel signals quality are proposed. It is found that the error codes in signal channels of the improved system at Yanmenguan Seismological Station are reduced, through comparing and analyzing real cases. The same measures for improving channel signals quality have effect on other stations and improve rate of system normal running of network and heighten availability of earthquake data.
