摘　　要：本文简要分析了Logistic映射混沌扩频序列的奇 /偶相关特性以及序列的有限长度效应对奇 /偶相关特性的影响 ;提出了一种EOELogistic映射混沌扩频序列的构造方法 .理论分析表明 ,EOELogistic映射有限长度扩频序列的奇 /偶相关特性较原序列有所改善 .In this paper,the odd/even correlation properties of Logistic Map chaotic spread spectrum sequences and the effect of the finite length of the sequences on their odd/even correlation properties are analyzed.A family of new sequences,named EOE Logistic Map chaotic spread spectrum sequences,is proposed.Theoretical analysis shows that the EOE Logistic Map chaotic spread spectrum sequences are better than the original sequences.The results of simulation verifies the correctness of the theoretical analysis.
