摘要
本文通过对时分多址直接序列扩频移动通信系统中的扩频调制单元的研究,运用计算机模拟分析技术,对优选扩频码方案进行了论证,并重点讨论了选码过程中的部分相关性问题。最终获得了一组实用性较强的优选码组。
Based on a study of the Spread Spectrum Modulation Unit of DS/TDM/TDMA Mobile Communication System,and by using the com- puter simulation analysis technique,this paper demonstrates a scheme of optimum seeking of spread spectrum sequences.The discussion is focu- sed on the partial-correlation of the sequences,arriving at a group of highly practicable optimum sequences.
