摘要
低维混沌映射序列具有类似白噪声的统计特性,可有效地用作扩频地址码,但有限精度问题影响了它在实际中的应用。本文提出了一种基于素数的拟混沌序列的产生方法能够很好地逼近理想的混沌映射,从而可产生大量具有良好相关性能的序列,对序列统计特性的分析验证了这一点。
Due to the white- noise-like statistical properties, low dimensional chaotic map sequences can be used as spread spectrum sequences. However, the problem of finite precision affects their applicability. Using a method based on prime number proposed in this paper, we can generate a great number of quasi-chaotic sequences which are good approximation to ideal chaotic sequences. Analysis on the statistical properties of sequences are also given.
