该代码是书籍源码，是matlab的书的源代码，里面是算法实例，(The source code is the book, the book is the matlab source code, which is the algorithm instance,)

扩频通信中PN码同步仿真实验，中间无任何错误，可直接使用(can use)

对一副人物照片进行局部人脸的识别后，再用混沌系统产生的序列进行加密。(After the local face recognition of a character picture, the sequence generated by the chaotic system is encrypted.)

小波包。整合了几篇小波包的文献，提供了小波包的整体概念认识，可以由此对小波包产生比较明了的理解，同时简单介绍了Matlab小波包工具箱的用法。(Wavelet packet. Integration of the literature several wavelet packet provides a conceptual understanding of the overall wavelet packet, wavelet packet can thus produce more clear understanding of, and briefly introduced the use of Matlab Wavelet Toolbox.)
