基于单向耦合提出一种只需传递一个驱动变量实现混沌系统广义投影同步方法.通过改变广义投影同步的比例因子,获得任意比例于原驱动混沌系统输出的混沌信号.由于只需传递一个信号,比起已有的方法具有更高的实用价值,理论推导和数值仿真进一步表明了该方法的有效性.最后,基于统一混沌系统的广义投影同步,给出了一种安全性更好的混沌保密通信方案.
Based on one-way coupling, a method of generalized projective synchronization of chaotic system is proposed, which transfers only one driving variable. By changing the proportionality factor of generalized projective synchronization, an arbitrary proportion of chaotic signals output from the original chaotic system is obtained. Compared with the existing methods, it has higher practical value, and the theoretical derivation and numerical simulation further prove the effectiveness of the method.Finally, based on the generalized projective synchronization of the unified chaotic system, a more secure chaos security is given Communication program.
