中文摘要：
混沌扩频序列具有良好的自相关特性，适合作为地址码用于DS-CDMA系统。文中对基于分段线性内映射的二值序列进行了设计。得到了自相关函数为符号交替、指数衰减的最优二值序列，该序列比高斯白序列在系统容量上有约15．5％的提高。
英文摘要：
Chaotic spreading sequences have good performance of auto-correlation, which make them ideal candidates of spreading sequences for asynchronous DS-CDMA systems. A discussion of the design of chaotic binary sequences based on piecewise linear maps is presented. Study results showed that the capacity of these sequences with alternating signs and exponentially decaying auto-correlation is bigger than that of Gauss White sequence by 15.5%, which suggests improved DS-CDMA systems with their application.
