摘　　要：文章提出了提高有线遥测地震仪的数据传输速率的一种新方法：相关编码技术。相关编码信号比AMI或HDB3编码的信号的数据传输速率可以提高一倍，从而提高地震勘探的效率。文章还讨论了相关编码的理论和方法，对相关编码在有线遥测地震仪中的应用进行了分析。A new method,i. e. correlative coding for the increasing of data transmission rate in cabled telemetry seismic instrument was put forward in this paper. The data transmission rate with correlative coding can be twice as high as that with AMI or HDB3, thus may improving the efficiency of seismic exploration. The theory of correlative coding was discussed and the application of it in cabled telemetry seismic instrument was analyzed in this artical.
