| 摘 要： | 以genesio-lorenz系统具有同步性为例,提出3种新方法来研究混沌保密通信:混沌遮盖,混沌参数调制,混沌键控,通过仿真验证了此类方法使通信系统的保密性更强,应用灵活,更适于硬件设计；又将此同步系统应用在扩频通信领域,通过研究信噪比和序列长度关系,可以得出一些结论.

| Abstract: | tarting from the fact that genesio-lorenz system is synchronized,three new methods are proposed to study the chaotic secure communication: chaos cover,chaotic parameter modulation,chaos shift keying.Simulation tests suggest such methods are featured with better confidentiality of communications systems,flexible application and better suitability for hardware design.This synchronization system can also be used in spread spectrum communications.Some conclusions have been reached after observing the relationsh... |
