摘    要:本文利用无限折叠迭代混沌映射产生二相与四相混沌扩频序列。分析了序列轨迹点具有的分布律与相关特性,模拟结果表明它们分别能获得比同等长度的二相与四相Logistic序列、四相Chebyshev序列、m序列、Gold序列更好的自相关与互相关性能,有利于解决CDMA移动通信中对相关性要求很严格的抗多址(多径)干扰、多用户检测等关键问题。

关 键 词:无限折叠迭代混沌映射  扩频序列  相关性  扩频通信

Abstract:Binary phase and quadri phase chaotic spreading sequences are produced using iterative chaotic map with infinite collapses(ICMIC) The distribution and correlation characteristics of such sequences are analyzed Simulation results show that they can achieve better performance than binary phase and quadri phase Logistic sequences,quadri phase Chebyshev sequences,m sequences and Gold sequences with same lengths It is very useful in solving key problems related to correlation characteristics in CDMA mobile communications,such as multiple access interference,multi path interference,multi user detection and so on
Keywords:iterative chaotic map with infinite collapses(ICMIC)  spreading sequences  correlation
