摘　　要：本文提出一种基于统一参数混沌系统的参数调制新方法。该方法根据统一参数混沌系统的特点,在发送端,用数字信息连续调制统一混沌系统的一个参数,使混沌系统的吸引子不断变化,数字信息信号直接隐藏在混沌系统的状态变量中。信道中传输混沌系统的状态变量。在接收端,对接收到的混沌状态变量进行间歇采样,并与接收端的混沌系统的状态变量进行误差比较,根据比较的结果来解调出数字信息。对该方案进行仿真,仿真结果证明方案的合理性。a new parameter modulation method based on the unified chaotic system is proposed in the paper. On the sender, the digital signal is used to modulate the parameter of the unified chaotic system, so makes the chaotic-attracter continuously change, the digital signal is embedded into the chaotic state signals. The chaotic states are transmitted through the channel. On the receiver, the received chaotic states are sampled discontinuously, and the comparison analyses are made between the samples and the chaotic states of the receiver. The digital signal can demodulate by the compared result. The simulation results show that the method discussed above is efficient.
