摘　　要：通过数学中码相关性的定义和计算方法,对TD-SCDMA系统扰码的相关性以及扰码和扩频码生成的复合码相关性进行了分析.以此为基础,提出了在TD-SCMDA系统网络规划中进行扰码规划的两种思路和方法,即分别以扰码相关性和复合码相关性为依据筛选性能较好的扰码进行分配和复用,以降低TD-SCMDA系统在同频组网时对相邻小区带来的多址干扰.Code planning is a very important part of TD-SCDMA radio network planning. The article first analyzes and explains the relativity of TD-SCDMA scrambling codes and complex codes. Then, based on the result of relativity, it proposes two methods to do the scrambling code reuse and planning. According to the code planning rule, it can reduce the interference form neighbor cell when the neighbor cells use the same frequency.
