摘要
对基于Chebyshev映射的混沌序列初值敏感性、平衡特性、相关特性进行仿真研究,将混沌序列应用在DS-CDMA系统中,与Gold码序列进行比较。结果表明,混沌序列与Gold码序列性能接近,具有生成简单、序列数目多、保密性好等优点,是替代传统扩频码的理想选择。
The initial value sensitivity,balance properties and correlation properties of chaotic sequences based on Chebyshev mapping are studied.Performance of chaotic sequences is compared with Gold sequences in DS-CDMA system.Simulation results show that chaotic sequences have approximately the same correlation properties as Gold sequences.As an ideal choice,it is easy to generate a large number of chaotic sequences with good security.
