一种新型的混沌直接扩谱序列

One New Kind of Chaotic Direct Spread ing Sequences

提出了一种基于一维无限折叠混沌映射的直接扩谱序列构造方法。统计测试和仿真结果表明,所产生的二值直接扩谱序为统计独立的均匀分布序列,因而具有理想的二值自相关函数和零互相关函数的特性。

This paper propose one method of constructing direct spreading sequences based on one -dimensional chaotic maps with i nfinite collapse.Statistical tests and simulations show that the two -valued direct spreading sequences a re statistically independent and un iformly distributed sequences,and have ideal toe -valued autocorrelation function and zero -valued cross c orrelation.
