摘 要: 本文对二进制混沌键控系统的单向耦合同步进行分析,导出耦合电阻与蔡氏电路参数之间的关系表达式。根据混沌信号的相关特性和文献[1]所提出的CSK原理,设计一种二进制混沌键控信号调制与相关解调的硬件实验系统,在此基础上进行了该系统的硬件实验研究。 Uni-directionally coupled synchronizing in CSK system is analyzed. The relationship between coupled resistance and Chua's circuit parameters is obtained. Based on the characteristics of chaotic signals and CSK principle given by reference [1], a coherent demodulation method for binary chaos shift keying signals is designed. On the basis of this research, hardware experiment has been demonstrated.
