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。
A method of constructing direct spread spectrum sequence based on one-dimensional infinitely folded chaotic map is proposed. The statistical test and simulation results show that the binary direct spread spectrum generated is a statistically independent uniform distribution sequence, which has the characteristics of ideal binary autocorrelation function and zero cross correlation function.
