生产现场测控信息码分多址传输技术研究

Study of CDMA Transmission Technology of Measured Data CDMA in Work Field

介绍采用基于直接序列扩频的码分多址原理 ,在强电磁干扰生产现场进行测控信息多路复用传输的实现技术 ,以及扩频与码分多址技术的有关原理。给出了伪码发生器的设计方法 ,和在具体应用中的实验测试结果。

The paper introduces the CDMA method based on direct sequence spread spectrum. With this method, the multiply transmission of measured data can be realized under the condition of strong narrow band interference in the production field. The principle of DS and the CDMA theory are also discussed in the paper. According to different applied places, some quality guarantee and improvement measures of pseudo random sequence generator are presented, and the experiment results are also given.
