【摘要】 实际通信信道中存在噪声,信号传输过程中有衰减和时延。为此,本文构造了时延反馈控制的混沌系统同步方案,在此基础上,通过调制系统参数,使其实现时延反馈控制状态下的参数自适应同步;并对时延反馈的参数词制混沌同步方案进行仿真分析,在信道存在噪声的情况下可以很好地解调恢复信号。更多还原

【Abstract】 Communication channels exist noise,information reduction and delays. Based on this point,a kind of time-delay feedback chaotic synchronization scheme is considered in this paper. which is applied with parameter adaptive control scheme. By Simulation, the controlling strategy can synchronize chaos systems under noise. When this method is used in secure communication, it is easy to recover the transmitted signal.更多还原
