摘要
本文分析了Ｌｏｇｉｓｔｉｃ 映射混沌扩频序列的奇／偶相关特性。定义了有限精度门限值概念。通过计算机仿真，得到了最大奇／偶相关绝对值与序列长度的渐近关系式和有限精度门限值与序列长度的经验公式。
This paper investigates the odd and even correlation properties of logistic map chaotic spread spectrum sequences The concept of the threshold of finite precision is defined By simulation,the approximate formula of the maximum absolute of the odd and even correlation in term of the length of the sequences and the approximate formula of the threshold of finite precision in term of the length of the sequences are obtained
