从Logistic -Map映射的表达式出发 ,经过一些数学推导得到了一个混沌序列 ,通过对其统计特性的数学表达式的分析 ,发现其与白噪声的统计特性一致 ,非常适合在扩频通信中用作扩频码 .但由于存在截取的问题 ,这种类随机序列的平衡性较差 .为了解决这一问题 ,本文提出了一种新的复合混沌扩频序列———mH序列 ,并采用了交织的方式较好地解决了这个问题 .仿真实验结果表明 ,复合混沌扩频序列具有良好的相关性和平衡性 ,并且具有很强的抗破译能力 . Starting from the expression of Logistic -Map mapping, a chaotic sequence is obtained through some mathematical derivation. By analyzing the mathematical expressions of its statistical properties, it is found that it is consistent with the statistical properties of white noise, which is very suitable for spread spectrum communication However, due to the problem of interception, this kind of random sequence has poor balance.In order to solve this problem, this paper proposes a new complex chaotic spread spectrum sequence --- mH sequence, and uses interleaving Which is a good solution to this problem.The simulation results show that the composite chaotic spread spectrum sequence has good correlation and balance and has strong anti-deciphering ability.
