摘要
详细分析Logistic映射的混沌序列对初始值的敏感性、非相关、近似熵复杂性等主要特性,并将其应用扩频通信系统中。仿真结果表明Logistic混沌序列具有传统扩频码序列的良好扩频特性。
It is investigated in detail the important properties for Logistic chaotic sequence, such as the sensibility to initial values, non -correlation property and complexity property, and the application in the spread - spectrum （SS） communication in this paper. Simulation results show that Logistic chaotic sequence possesses the same properties as conventional spread- spectrum sequences.
