摘要
分析了TD-SCDMA系统中复合扩频码相关特性,在此基础上构建扰码对的互相关值评价矩阵,提出了基于码字相关值的扰码规划方法。通过对下行同步码和复合扩频码的分析可以发现,在实际的规划中,应该以分配下行同步码为中心,逐步筛选,得到最合适的扰码。最后,在网络优化软件中实现了提出的新方法。
The correlation of the complex sp correlation value of evaluation matrix about planning algorithm based correlative value is reading code in TD -SCDMA system is analysed, the cross - complex spreading code is constructed, and a scrambling code proposed which is the weight of code disturbs mutually. Analysis of complex spreading codes and downlink synchronization codes shows that first ensuring the downlink synchronization codes in the adjacent cell does not re -use, thereby ensuring the correlation between scrambling spreading codes and neighbor cell' s scrambling spreading code is the best. Finally, the proposed new method is implemented in the network optimization software.
