| 摘 要： | 在这系列文章的第一部分，我们提出了一种状态空间模型的估计算法。第二部分将该算法应用于混沌调制通信系统的解调。当“扮演”系统参数的信息信号被建模为AR模型后，混沌调制通信系统的解调问题可转化为对增广的状态空间模型的估计。仿真结果表明，该算法也能有效地实现混沌调制通信系统的自适应解调。

| Abstract: | In the first part of this series papers, we have proposed an estimation algorithm for the extended state space model, which will be used to realize the demodulation for chaotic modulation communication systems in the second part. When message signals acting as the systematic parameter are modeled as AR models, the issues of demodulation for chaotic modulation communication systems are transferred into the ones for estimation extended state space models. The results by computer simulation that the algorithm can be used to realize the demodulation for chaotic modulation communication systems as well. |
