| 摘 要： | 针对当前混沌扩频序列复杂度低、产生方法单一的不足,提出了一种高效的基于嵌入式模型产生混沌扩频序列的方法,并将生成的混沌序列应用于直接序列扩频系统。理论分析和仿真表明:该方法生成的混沌序列不仅复杂度高、保密性好,具有良好的相关性能,而且能够同时产生大量的混沌扩频序列,极大地提高了生成效率,有一定的实用价值。

| Abstract: | In order to avoid the disadvantages of low complexity and single generating scheme of the current chaotic spread spectrum sequence,a efficient scheme of generating chaotic spread spectrum sequences based on embedded model is put forward in the paper,and the generating chaotic sequences will be applied to the direct sequence spread spectrum system.The theoretical analysis and simulation results show that the scheme of generating chaotic sequences are not only high complexity,good secrecy,good performance,and... |
