提出了一种基于收缩映射的混沌键控信号解调方案，给出了系统误码性能的数学表达式。该方案将所传输的数字信号映射为混沌系统的两种不同的同步相位，再利用接收端提供的同步信号将其提取出来。仿真结果表明，该方案能够快速实现同步，有较强的鲁棒性，同时系统结构也较为简单
A scheme of chaotic keying signal demodulation based on contraction mapping is proposed, and the mathematical expression of system error performance is given. In this scheme, the transmitted digital signals are mapped into two different synchronization phases of the chaotic system and then extracted using the synchronization signal provided by the receiver. The simulation results show that the scheme can achieve synchronization quickly, has strong robustness and the system structure is relatively simple
