摘　　要：通过建立Logistic满映射混沌模型,产生Logistic满映射混沌模拟序列,再进行二值量化后,利用Matlab 7.0对其性能进行仿真分析。主要分析其初值敏感性、相关性、平衡性、遍历性、相空间及倍周期分岔特性。分析结果表明,Logistic满映射混沌序列具有良好的自相关性、互相关性、平衡性,而且其序列数量众多,其性能优于传统的伪随机序列。该序列可广泛用于数字加密、扩频通信等领域中。To produce Logistic full mapping chaos analog sequence,a Logistic full mapping chaos model is built, and then it is guantified two level digital sequence. The performance analysis of this chaotic sequence is carried out by use of Matlab 7.0 simulation. Senstivity of initial value,correlation, balance, ergodic, phase dimensional and double- periods forks characteristic are mainly analyzed. The analysis results show that the performance of this chaotic sequence is better than that of traditional pseudo random sequences for more well correlative performance and balance performance,and their number is large. It can be widely used in digital encryption and spread spectrum communcation.
