【摘要】 混沌信号对初始条件的敏感,使得目前混沌信号在通信系统的收发端难以建立同步,实际应用中基于同步的混沌信号相干检测技术还不很成熟。通过采用一种基于概率统计的方法,应用最大似然法和贝叶斯公式,在CSK(ChaosShiftKeying)系统的接收端重构发射端混沌映射,实现混沌信号的非相干检测。在一定的信噪比条件下,理论推导和计算机仿真结果是一致的。更多还原

【Abstract】 It is hard for chaotic signals between transmitter and receiver to realize synchronization now.This paper presents a kind of noncoherent detection technology for chaotic signal based on probabilistic method.The method consists of maximumlikelihood and Bayesian formulation.Nonconherent detection is realized by the reconstruction of chaotic signal at CSK receiver.更多还原
