用于混沌扩频保密通信的不等长四相扩频序列

Chaotic 4-phase spreading sequences with inequal length for the application in secrecy communication

本文重点研究不等长四相混沌扩频序列的广义奇互相关性质。理论分析和仿真实验表明 ,不等长与等长的四相混沌扩频序列在许多方面具有相似的性质 ,所获结果为不等长四相混沌扩频序列在保密通信等方面的应用提供了理论基础。

This paper mainly discusses the generalized odd cross correlation of chaotic 4-phase spreading sequences with inequal length.Analysis and simulations show that 4-phase sequences with inequal length have similar qualities to ones with equal length in many aspects.The obtained results provide the basis for the application of chaotic 4-phase sequences with inequal length in secrecy communication.
